Properties of yeast pyruvate decarboxylase and their modification by proteolytic enzymes : I. Stability of decarboxylases from wild-type and mutant strains
(Elsevier, 1968)
High concentrations of inorganic phosphate and ammonium sulfate stabilize yeast pyruvate decarboxylase to heating at 60 [deg] for long periods of time in the presence of TPP and Mg+. When heated at 60 [deg] in phosphate ...
A polarographic method for following the rates of cholinesterase-catalyzed hydrolyses of acetylthiocholine
(Elsevier, 1965-08)
A rapid and simple polarographic method for following the rates of the cholinesterase-catalyzed hydrolysis of acetylthiocholine and the rates of inhibition of this hydrolysis is described. This method has the advantage ...
Gas chromatographic separtion of low molecular weight fluorocarbons
(Elsevier, 1968)
Application of gas-solid chromatography techiques to the separation of low molecular weight fluorocarbons incorporates a number of advantages over previous analysis techniques. These advantages include isothermal operation ...
Conversion of dehydroepiandrosterone sulfate to androst-5-enediol-3-sulfate by soluble extracts of rat testis
(Elsevier, 1965-09)
3H-Androst-5-ene-17-one-3[beta]-y1 sulfate is converted to 3H-androst-5-ene-17[beta]-o1-3[beta]-y1 sulfate by soluble extracts of rat testis in the presence of added NADH2 or NADPH2.The conversion was approximately 4 times ...
Metabolism of triphenylmethane and triphenylcarbinol
(Elsevier, 1964-08)
A study of the metabolism of triphenylmethane and triphenylcarbinol in the rabbit indicates that the major urinary metabolite of these two compounds is the corresponding glucuronide. When 1 gm of triphenylmethane is fed ...
Protein-carbohydrate interaction : VIII. A turbidimetric method for the analysis of -mannose
(Elsevier, 1967-08)
A unique, spectrophotometric method for the quantitative of -mannose in the presence of other sugars is described. The procedure depends on the degree to which the turbidity formed on interaction of concanavalin A with ...
Effect of chloride lons on the reaction of diphenylamine with DNA
(Elsevier, 1965-08)
The sensitivity of the Dische test (diphenylamine) for DNA is reduced by the presence of chloride ions, which cause formation of a new reaction product whose absorption maximum is at lower wavelength, and also a reduction ...
Hydrogenation of testosterone sulfate by the [Delta]4-3-ketosteroid reductase of rat liver microsomes
(Elsevier, 1965-01)
TPNH2 is oxidized in the presence of testosterone or testosterone sulfate and a microsomal preparation from the liver of female rats. In the presence of iorganic phosphate, DPNH2 also acts as a hydrogen donor. Evidence is ...
