resistance to levomycetin and activity of several enzymes in escherichia coli and the agent of plague.the authors compared the activity of acetyl-coa-synthetase and of the enzymes belonging to the group of asparaginic acid in levomycetin sensitive and resistant strains of y. pestis and e. coli. there were revealed marked differences in the activity of aspartase, fumarase, synthetase and desamidase of l-asparagin, and also of the enzyme activated by acetate in the e. coli strains with plasmide resistance. transmission of r-factor to the pestis was accompanied by decomposition of l-asparadein, for ...19768940

[on the biophysical interpretation of ageing-factors (author's transl)].the ageing-factor is a measure for the rate of ageing. in the model of vitality the error rate mu corresponds to the ageing-factor. the ageing-factors of several physical functions can be determined from the ascent of decrease of these functions. the standardized ageing-factors of the considered physiological functions range from 0.001 to 0.017 year--1 and are smaller than the ageing-factor of the whole organism. the date of the occurrence of pathological manifestations as a result of ageing-con ...200014551

purification and properties of the methane mono-oxygenase enzyme system from methylosinus trichosporium ob3b.1. a three-component enzyme system that catalyses the oxidation of methane to methanol has been highly purified from methylosinus trichosporium. 2. the components are (i) a soluble co-binding cytochrome c, (ii) a copper-containing protein and (iii) a small protein; the mol. wts. are 13 000, 47 000 and 9400 respectively. the cytochrome component cannot be replaced by similar cytochrome purified from pseudomonas extorquens or by horse heart cytochrome c. 3. the stoicheiometry suggests a mono-oxyge ...197715544
binding rates, o--s substitution effects, and the ph dependence of chymotrypsin reactions.the ph dependence for acylation of alpha-chymotrypsin by n-acetyltryptophan p-nitrophenyl-, p-nitrothiophenyl-, ethyl-, and thiolethyl esters has been studied by the stopped-flow technique. values for the acylation rate constant, k2, and the binding constant, ks, were obtained by using measurements of phenolate release, for the p-nitrophenyl esters, and proflavin displacement, for the ethyl esters. the oxygen esters tested have slightly higher k2 values, and substantially higher ks values relati ...200015586
an investigation of heavy meromyosin-adp binding equilibria by proton release measurements.the interaction of magnesium-adp with skeletal muscle heavy meromyosin has been studied by measuring the accompanying release of protons. total ph changes of the order of 0.03 were involved, and measurements were performed with a discrimination of some ten-thousandths of a ph unit. at ph 8.0 and 25 degrees c about 0.5 mol of protons per mol of heavy meromyosin is released at saturation. a stoichiometry of binding close to 2 mol of adp per mol of protein was found, with a binding constant, obtain ...197715588

testicular androgen binding protein (abp) - a parameter of sertoli cell secretory function.using abp as an index of sertoli cell secretory function, several important features of the sertoli cell have emerged: 1. the stimulation of abp production by fsh clearly points to the sertoli cell as a target cell for fsh (3,4,9-16,21,24). 2. the dramatic effects of androgens on abp production both in immature and mature rats also suggest that the sertoli cell is a target cell for androgen (3,12,14,16,25). 3. the striking reduction in abp production in the cryptorchid testis raises the question ...197518322

aerobic glycolysis in bone: lactic acid production by rat calvaria cells in culture.considerable data have been accumulated on aerobic glycolysis of intact bone preparations. to test whether aerobic glycolysis is a feature of the bone cells themselves or of the localized conditions within an intact bone, cells isolated from rat calvaria were cultured and the effect of several factors on lactate production was determined. these cells drastically decreased lactate production when the ph in the culture medium was lowered, changing from 100 to 20 percent for a ph shift from 7.4 to ...197823680
