The foetal development of lactate dehydrogenase isoenzymes, glucose 6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase from human striated muscle.

On the distribution and characteristics of isozyme expression in Mycoplasma, Acholeplasma, and Ureaplasma species.

A summary of a survey of three genera of mycoplasmatales (Mycoplasma, Acholeplasma, and Ureaplasma) for isozyme expression is presented. Isozyme analysis of mycoplasmas has been employed in at least three distinct areas: (1) as genetic markers for identification, individualization, and taxonomic classification; (2) as markers for cell culture contamination; and (3) as a qualitative measure of t...

Studies on the enzymology of the rhabdomyosarcoma induced by the murine sarcoma virus (Moloney).

SUMMARY The murine sarcoma virus (Moloney) induces a rhabdomyo sarcoma in adult mice followed by a high incidence of regressions. Changes in several biochemical parameters and enzyme levels were followed during the enlargement and regression of the tumor. As the tumor enlarged, water, protein, RNA, and DNA concentrations increased on a dry weight basis. Actomyosin free Mg@@-activated ATPase and...

Inhibition of Human Erythrocyte Glucose 6-Phosphate Dehydrogenase by Cadmium, Nickel and Aluminium

Glucose degradation in Clostridium perfringens type A.

Cell-free extracts of Clostridium perfringens were found to contain all the enzymes of the Embden-Meyerhof pathway of glycolysis in addition to lactic acid dehydrogenase and the pyruvate-clastic system. Neither glucose-6-phosphate dehydrogenase nor 6-phosphogluconate dehydrogenase activities could be demonstrated, suggesting the absence of the conventional hexose-monophosphate pathway in this o...

A comparative study of some of the enzymes involved in glucose metabolism of human diploid and SV40-transformed human diploid cells.

All of the glycolytic enzymes with the exception of enolase and phosphoglyceromutase were measured for WI-38, human embryonic lung tissue, and its SV40-transformed counterpart, WI-38VA13A. Also measured were glucose 6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, phosphoglucomutase, and fructose 1,6-diphosphatase. Enzyme activity per IO6 cells indicated that glucose 6-phosphate deh...
