| studies with lectins on the surface carbohydrate structures of mycoplasma membranes. | the surface carbohydrate structures on the cell membranes of various mycoplasma species have been investigated by using lectins, which are sugar-specific proteins. carbohydrate structures presumably bound to glycolipids, with both galactose and glucose units, were found to be exposed on the surface of mycoplasma pneumoniae and its temperature-sensitive mutants, m. mycoides var. mycoides and capri, m. pulmonis, m. gallinarum, and m. gallisepticum. lipid-bound glucose was found on m. neurolyticum. ... | 1974 | 4138526 |

| use of the avidin-biotin complex for specific staining of biological membranes in electron microscopy. | to expand the electron microscopist's options in localization and visualization, a new and general staining technique has been tested. the avidin-biotin complex serves as a coupling between the electron-dense marker, ferritin, and points of interest in biological samples. when specific cellular components are tagged with biotin, those components may be visualized with ferritin-linked avidin. because of the remarkably strong affinity of avidin and biotin (characterized by an association constant ... | 1974 | 4139715 |

| immunological analysis of glycolipids and lipopolysaccharides derived from various mycoplasmas. | the lipids and lipopolysaccharides of five mycoplasmas were examined for complement-fixing activity to antimembrane rabbit sera. total glycolipid fractions and the aqueous phenol fractions (lipopolysaccharides) from the membranes of acholeplasma laidlawii, a. modicum, a. axanthum, and mycoplasma neurolyticum exhibited significant antigenic activity. the glycolipids and phosphoglycolipids from thermoplasma acidophilum were either anticomplementary or did not react due to their extreme hydrophobic ... | 1974 | 4215761 |

| differential effect of phenethyl alcohol on mycoplasmas and enveloped viruses. | mycoplasmas are totally inactivated by a 20-min treatment with 1% phenethyl alcohol, whereas suspensions of enveloped viruses resist the same treatment. this treatment has proved successful in eliminating mycoplasma contamination of a virus suspension. | 1974 | 4372415 |

| induction of interferon in mice by mycoplasmas. | interferon was induced in mice after intraperitoneal inoculation with four different mycoplasmas. peak levels of between 100 and 300 u of interferon per ml were attained by 6 h postinfection with each of the mycoplasmas except mycoplasma arthritidis, which induced higher titers (400 to 11,800 u/ml) by this time. a fifth mycoplasma, m. pulmonis, induced interferon inconsistently and at a later (72 to 96 h) time. mycoplasmatales virus mvl51 and sterile mycoplasmal broth did not stimulate interfero ... | 1974 | 4373395 |

| interaction of mycoplasma with viruses. i. primary adsorption of virus is ionic in mechanism. | we have studied the adsorption of the gourlay acholeplasma virus mvl-1 to the host cell acholeplasma laidlawii ja-1. successful adsorption depends primarily on some unknown action of the serum factor in the medium, but evaluation of various physical parameters indicates clearly that given this factor the kinetics is pseudo first order (k = 3 x 10(-9) cm(3)/min) and the mechanism ionic. chiefly important are the ionic strength of the cation and ph (optimal na(+) = 0.08 m, ph = 6). the system seem ... | 1974 | 4824711 |

| spiroplasmas are the causal agents of citrus little-leaf disease. | a spiroplasma isolated from citrus with little-leaf disease was grown in a cell-free medium and injected into leafhoppers (euscelis plebejus). injected leafhoppers, but not those fed on infected plants, transmitted the spiroplasma to white clover (trifolium repens cv. s100) and sweet orange (citrus sinensis cv. valencia). infected clover plants were severely stunted; infected sweet orange plants showed typical symptoms of citrus little-leaf disease. the spiroplasma was detected in clover and swe ... | 1974 | 19280788 |
| divalent cations in native and reaggregated mycoplasma membranes. | the mg(2+) content of membranes of several mycoplasma and acholeplasma species varied between 0.88 and 1.98 mug of mg(2+) per mg of protein, depending on the species and on growth conditions. ca(2+) could be detected only when it was added to the growth medium. the mg(2+) content of isolated a. laidlawii membranes could be increased almost threefold by dialysis against 20 mm mg(2+), whereas aggregated a. laidlawii membranes contained about six to eight times more mg(2+) per mg of protein than th ... | 1973 | 4632319 |
| freeze-fractured acholeplasma laidlawii membranes: nature of particles observed. | freeze-fracture of acholeplasma laidlawii membranes from cells incubated in the presence of puromycin or omission of amino acids reveals a decrease in the number of particles between 50 and 100 angstroms in the hydrophobic fracture plane, which strongly suggests that these particles are protein. additional evidence indicates that they may be involved in substrate transport. | 1973 | 4682132 |

| properties of a fructose-1,6-diphosphate-activated lactate dehydrogenase from acholeplasma laidlawii type a. | acholeplasma laidlawii a possesses a nicotinamide adenine dinucleotide (nad)-dependent l(+)-lactate dehydrogenase (ldh) which is activated specifically by low concentrations of fructose-1, 6-diphosphate (fdp). studies with partially purified enzyme show that the kinetic response to fdp is hyperbolic. the enzyme is inhibited by inorganic phosphate, adenosine triphosphate, and high concentrations of reduced nad (nadh). low activity is demonstrable in the absence of fdp at ph 6.0 to 7.2, but fdp is ... | 1973 | 4712565 |

| fusion of phospholipid vesicles with viable acholeplasma laidlawii. | when vesicles of dipalmitoyl phosphatidylcholine produced by sonication are mixed with acholeplasma laidlawii in neutral buffer, a phenomenon occurs that is most readily explained in terms of fusion of lipid vesicle membrane with the mycoplasma cytoplasmic membrane. the mycoplasma can readily accumulate large quantities of the foreign lipid without loss of viability. the added lipids do not remain in patches but diffuse laterally throughout the mycoplasma membrane. | 1973 | 4515622 |

| acyl carrier protein in mycoplasmas. | acyl carrier protein (acp) activity was determined by the malonyl-coenzyme a-co(2) exchange reaction. it was highest in acholeplasma laidlawii, lower in a. granularum, and lowest in a. axanthum. the sterol-requiring mycoplasma species examined showed little or negligible acp activity. a. laidlawii was capable of utilizing pantetheine or coenzyme a but not beta-alanine as precursor for acp synthesis. its acp could thus be labeled by growing the organisms with radioactive coenzyme a. the acp of a. ... | 1973 | 4570599 |
