| nucleoside diphosphokinase activity associated with dna polymerases. | nucleoside diphosphokinase activity is present in highly purified preparations of dna polymerase from micrococcus luteus and escherichia coli, and in a partially purified dna polymerase from avian myeloblastosis virus. the activity is also observed in the protein fragment of molecular weight 76,000 that is produced by subtilisin cleavage of dna polymerase i from e. coli. the ndp kinase activity in dna polymerase preparations from m. luteus uses various ribo- and deoxyribonucleoside di- and triph ... | 1971 | 4332252 |
| primer requirement and template specificity of the dna polymerase of rna tumor viruses. | polyribonucleotides will act as efficient templates for the dna polymerases found in the virions of avian myeloblastosis virus and mouse leukemia virus if a short complementary oligodeoxyribonucleotide primer is added. synthesis of the complementary polydeoxyribonucleotide continues until an amount of polymer equal to the amount of initial template has been produced. the two viruses show slightly different specificities toward the four homoribopolymers. polydeoxyribonucleotides are generally muc ... | 1971 | 4327004 |

| base composition differences between avian myeloblastosis virus transfer rna and transfer rna isolated from host cells. | using a novel chemical tritium derivative method, we have determined the base composition of 4s rna isolated from an rna tumor virus, the avian myeloblastosis virus, and from normal and neoplastic host cells. extensive differences were detected, particularly with respect to the amount of methylated bases in the viral rna. the viral 4s rna, which fulfills the criteria for designation as transfer rna, appears to be derived from a precursor pool that is different from the precursor population of ho ... | 1971 | 4332019 |
| ultrastructural comparison of a virus from a rhesus-monkey mammary carcinoma with four oncogenic rna viruses. | the ultrastructure and morphogenesis of mason-pfizer monkey virus, isolated from a mammary carcinoma in a rhesus monkey, was compared with those of murine mammary tumor virus, murine leukemia virus, l1210 leukemia-associated virus, and avian myeloblastosis virus. the simian virus resembled murine mammary tumor virus and the l1210 virus in that it produced intracytoplasmic particles that were enveloped during budding. it resembled l1210 virus and murine leukemia virus in budding with smooth envel ... | 1971 | 4327008 |

| helical nucleocapsid structure of the oncogenic ribonucleic acid viruses (oncornaviruses). | negative staining of virions and isolated nucleoids from avian myeloblastosis virus, murine leukemia virus, murine mammary tumor virus, and feline leukemia virus reveals common internal structures. the majority of virions that are penetrated by phosphotungstate show spherical nucleoids with no apparent symmetry. in a small percentage of virions, two distinctive structures are found: (i) single strands (3 to 5 nm in diameter) which are presumed to be the nucleoprotein and are found randomly orien ... | 1971 | 4108573 |
| deoxyribonucleic acid polymerase associated with avian tumor viruses: secondary structure of the deoxyribonucleic acid product. | the products of the deoxyribonucleic acid (dna) polymerase associated with rous sarcoma virus and avian myeloblastosis virus were characterized by correlative analyses with equilibrium centrifugation and stepwise elution from hydroxyapatite. the initial enzymatic product consists of nascent dna chains which are hydrogen-bonded to 70s viral ribonucleic acid (rna), whereas the final enzymatic product is double-stranded dna. appreciable amounts of free single-stranded dna were not detected at any p ... | 1971 | 4322606 |

| surface-active agents for isolation of the core component of avian myeloblastosis virus. | sixty-one surface-active agents were evaluated in a procedure designed to assess their ability to remove the envelope from the core component of avian myeloblastosis virus (amv). the procedure consisted of centrifugation of intact amv through a series of sucrose gradients each containing an upper layer of agent at one of eight concentrations between 0.01 and 10%. the effectiveness of an agent in producing amv cores was indicated by (i) the appearance of light-scattering bands in the region of co ... | 1972 | 4112071 |
| viral and cellular dna polymerase: comparison of activities with synthetic and natural rna templates. | two dna polymerases purified from normal human lymphocytes are distinguishable from the viral reverse transcriptases of avian myeloblastosis virus and mason-pfizer monkey virus by their relative affinity for select templates. in this respect, the activity of the two normal human lymphocyte polymerases closely resembles the activity of escherichia coli dna polymerase 1. the viral and cellular dna polymerases are equally active with the nonspecific template, poly(ra) . poly(dt). criteria for disti ... | 1972 | 4113240 |
| serological analysis of the deoxyribonucleic acid polymerase of avian oncornaviruses. i. preparation and characterization of monospecific antiserum with purified deoxyribonucleic acid polymerase. | monospecific antiserum was prepared against purified deoxyribonucleic acid (dna) polymerase from avian myeloblastosis virus (amv). immunodiffusion assay with purified dna polymerase revealed that the anti-dna polymerase serum formed one precipitation band, whereas no reaction with any of the seven major structural proteins of amv was observed. the antiserum also demonstrated enzyme-neutralizing antibody activity that was associated with the immunoglobulin g fraction. there was no difference in t ... | 1972 | 4117965 |
| serological analysis of the deoxyribonucleic acid polymerase of avian oncornaviruses. ii. comparison of avian deoxyribonucleic acid polymerases. | monospecific antiserum prepared against the isolated deoxyribonucleic acid (dna) polymerase of avian myeloblastosis virus (amv) neutralized the endogenous ribonucleic acid-instructed dna polymerase activity of detergent-disrupted virus. the viral polymerase was serologically unrelated to the seven major structural polypeptides of amv. furthermore, the viral enzyme was distinguished from normal cellular dna polymerases by serological criteria; thus, antiserum against the viral enzyme neutralized ... | 1972 | 4117966 |

| isolation and characterization of a protein that stimulates dna synthesis from avian myeloblastosis virus. | a protein has been isolated from avian myeloblastosis virus that stimulates the rate and yield of dna synthesis primed by viral rna with purified viral polymerase. it specifically affects the viral polymerase and does not stimulate other dna polymerases under the conditions tested. the viral polymerase, in conjunction with this protein, transcribes extended single-stranded regions of dna, and permits the enzyme to initiate synthesis from single-strand breaks in dna. | 1972 | 4340754 |
| distribution of deoxyribonucleic acid complementary to the ribonucleic acid of avian myeloblastosis virus in tissues of normal and tumor-bearing chickens. | (3)h-labeled 70s ribonucleic acid (rna) from purified avian myeloblastosis virus (amv) was used as a probe in deoxyribonucleic acid (dna)-rna hybridization experiments to detect the presence of dna complementary to the amv genome in various tissues from noninfected normal chickens and from chickens infected with amv. there was a remarkable constancy in the average cellular concentration of virus-specific dna found in every tissue from the same uninfected chicken, and even in different chickens f ... | 1972 | 4344249 |

| widespread presence, in chickens, of dna complementary to the rna genome of avian leukosis viruses. | dna-rna hybridization experiments have demonstrated the widespread presence in chickens of dna complementary to the rna of avian myeloblastosis virus. all apparently normal chicken embryos, or adult chickens that were tested, contained viral dna in amounts ranging from 1.7 to 4.6 viral genome equivalents per cell. embryos that were negative or positive for the group-specific antigen of avian leukosis viruses contained the same amount of viral dna. embryos from a strain of chickens free of leukos ... | 1972 | 4335067 |
| the genome of rna tumor viruses contains polyadenylic acid sequences. | the 70s genome of two rna tumor viruses, murine sarcoma virus and avian myeloblastosis virus, binds to millipore filters in buffer with high salt concentration and to glass fiber filters containing poly(u). these observations suggest that 70s rna contains adenylic acid-rich sequences. when digested by pancreatic rnase, 70s rna of murine sarcoma virus yielded poly(a) sequences that contain 91% adenylic acid. these poly(a) sequences sedimented as a relatively homogenous peak in sucrose gradients w ... | 1972 | 4337237 |
| the 3'-terminal nucleosides of the high molecular weight rna of avian myeloblastosis virus. | the rna isolated from avian myeloblastosis virus was fractionated by sucrose density gradient centrifugation. the 3'-oh terminal nucleosides of various fractions were determined by periodate oxidation followed by tritiated borohydride reduction. the 60-70s fraction and the 35s rna derived from it by heating both have adenosine as the major terminal nucleoside, with cytidine as the next most frequent terminal. control samples of trna(met) (f. coli) and 28s ribosomal rna from mouse ascites tumor c ... | 1972 | 4338584 |

| endogenous rna-directed dna polymerase activity in uninfected chicken embryos. | early chicken embryos that are either positive or negative for group-specific antigens of avian leukosis viruses contained endogenous rna-directed dna polymerase activity. this endogenous dna polymerase activity was not increased after mixture of soluble dna polymerases isolated from chicken embryos with disrupted chicken embryo cells. the endogenous activity was resistant to treatment with deoxyribonuclease, and the initial rate of dna synthesis was partially resistant to actinomycin d. in cont ... | 1972 | 4338597 |
| rna-primed dna synthesis in vitro. | in vitro dna synthesis on single-stranded circular dna can be initiated by rna primers. rna chains are covalently extended by dna polymerase ii from kb cells and dna polymerase i from micrococcus luteus, but not by an rna-dependent dna polymerase from avian myeloblastosis virus. the reaction product consists of dna chains with a piece of rna at their 5'-ends, hydrogen bonded to the template dna. the primer rna is linked to the product dna via a 3':5'-phosphodiester bond, and can be specifically ... | 1972 | 4338598 |
| degradation of dna rna hybrids by ribonuclease h and dna polymerases of cellular and viral origin. | ribonuclease h from human kb cells, chick embryos, calf thymus, avian myeloblastosis virus, and rous associated virus specifically degrades the rna of dna.rna hybrids, producing mono- and oligoribonucleotides terminated in 5'-phosphates. the cellular rnase h is an endonuclease, whereas the viral enzyme appears to be an exonuclease. viral dna polymerase and rnase h copurify through all separation steps. therefore, rnase h activity is an intrinsic part of the viral dna polymerase. dna.rna hybrids ... | 1972 | 4343966 |

| covalent linkage between ribonucleic acid primer and deoxyribonucleic acid product of the avian myeloblastosis virus deoxyribonucleic acid polymerase. | initiation of deoxyribonucleic acid (dna) synthesis by the avian myeloblastosis virus dna polymerase was previously suggested to involve a ribonucleic acid (rna) primer, the initial product being a dna molecule joined by a phosphodiester bond to the rna primer. the existence and nature of such an rna-dna joint was investigated by assaying for transfer of a (32)p atom from an alpha-(32)p-deoxyribonucleotide to a 2'(3')-ribonucleotide after alkaline hydrolysis of the polymerase product. such a tra ... | 1972 | 16789134 |

| separation of dna sequences complementary to the rna of avian myeloblastosis virus from chicken dna by alkaline cesium chloride density sedimentation. | density gradient sedimentation in alkaline cesium chloride of dna from normal chicken embryos or leukemic myeloblasts fragmented to a size of 13s revealed that the dna sequences complementary to 70s avian myeloblastosis virus rna sedimented in the high guanine plus cytosine region ahead of the main peak of cellular dna. when the dna was fragmented into pieces of 6.6s there was a broader distribution of the dna sequences complementary to the viral rna. this technique could be employed as a step t ... | 1973 | 4355853 |
