| deoxyribonuclease iv: a new exonuclease from mammalian tissues. | an exonuclease which specifically degrades double-standard dna has been isolated from rabbit tissues. the enzyme has an approximate molecular weight of 42,000, requires a divalent metal ion as cofactor, and attacks dna at the 5'-terminal ends, thereby liberating 5'-mononucleotides. it degrades several synthetic polydeoxynucleotides of single repeating base sequences more rapidly than dna from natural sources. the specificity of this mammalian enzyme resembles that of several microbial enzymes (p ... | 1969 | 5256235 |

| inactivation of bacteriophage lambda containing semiconserved alkylated deoxyribonucleic acid. | immediate and delayed inactivation of ethylmethane sulfonate (ems)-treated lambda phage were studied. phage particles with one alkylated and one intact deoxyribonucleic acid (dna) strand were obtained by allowing host-modified, ems-treated phage to undergo one growth cycle in a nonmodifying host and selecting the progeny with semiconserved parental dna on a restricting host. the results indicate that particles with one alkylated dna strand are more sensitive to a second treatment with the alkyla ... | 1969 | 5823226 |

| characteristics of some multiply recombination-deficient strains of escherichia coli. | strains of escherichia coli have been made carrying lesions in more than one gene determining recombination. the following genotypes were constructed and verified: recc22 recb21 reca(+), recc22 recb21 reca13, recc22 recb(+)reca13, and recc(+)recb21 reca13. all multiple rec(-) strains carrying reca13 were similar to ab2463, which carries reca13 alone, in their uv sensitivities, recombination deficiencies, and inabilities to induce lambda phage in a lysogen. however, whereas ab2463 shows a high ra ... | 1969 | 4898990 |
| leakiness of pleiotropic maltose-negative, bacteriophage lambda-resistant mutants of escherichi coli k-12. | cultures of escherichia coli k-12 mala(-)lambda(r)gal(-) can be transduced to gal(+) by bacteriophage lambdadg because of leakiness of the lambda(r) phenotype. the efficiency of such transduction is about 10(-5) that of transduction of mal(+)lambda(s) bacteria. leaky cells (lambda(s)phenocopies) adsorb only very few phage particles, and many transductants, therefore, are defective heterogenotes or show integration of the gal(+) gene, which is unaccompanied by lysogenization. | 1969 | 4905538 |

| effect of mutation to streptomycin resistance on amber suppressor genes. | three classes of nonidentical streptomycin-resistant mutations were distinguished in escherichia coli by their effect on the efficiency of suppression by an amber suppressor gene, sup e. the first class of mutation caused a strong restriction in efficiency of suppression of an amber codon in various cistrons of phage lambda and in an alkaline phosphatase structural gene of e. coli. the second class caused weak restriction, and the third class caused no restriction. the restrictive effect of the ... | 1968 | 4874314 |
| properties of mitomycin c-sensitive mutants of escherichia coli k-12. | strains hypersensitive to mitomycin c (mc) were isolated from escherichia coli k-12 after treatment with nitrosoguanidine. of 43 mc-sensitive strains tested for their ultraviolet light (uv) sensitivity and for their ability to reactivate uv-inactivated lambda phage, 38 were found to be insensitive to uv irradiation and to be able to reactivate uv-irradiated bacteriophage lambda. some properties of the mc-sensitive, uvr(+) mutants were analyzed. synthesis of deoxyribonucleic acid (dna) in mc-sens ... | 1968 | 4867746 |
| effect of lysogeny on serum sensitivity. | when escherichia coli k-12 was infected with lambda phage and mutants of lambda characterized by the production of temperature-sensitive repressors, the lysogenic bacteria were significantly more resistant to normal serum than the uninfected organisms. infection of e. coli k-12 with a lambdoid phage, phi80, whose prophage attachment site is different from that of lambda, did not result in a detectable change in serum resistance. similarly, infection with certain pseudomonas and shigella phages c ... | 1968 | 4881698 |
