Lactic and Α-glycerophosphate Dehydrogenases in Insects
Different tissues, especially muscles, from insects belonging to various groups were extracted and studied for their lactic dehydrogenase (LDH) and alpha-glycerophosphate dehydrogenase (GDH I) activities from the comparative point of view. In all cases assays of flight muscle extracts showed extremely low values of LDH activity whereas the GDH activities were surprisingly high. The activities i...
متن کاملAlpha-glycerophosphate and lactic dehydrogenases of hematopoietic cells from leukemic mice.
Bone marrow cells, lymphocytes, lymph nodes, solid lymphoid tumors, spleen and ascites cells from mice implanted with leukemia have markedly decreased o-glycerophosphate and increased lactic dehydrogenase activities. A striking parallel between the ratio of these dehydrogenases and the progression of the leukemia was found. These data, in conjunction with related findings, suggest that the a-gl...
متن کاملThe Lactic Dehydrogenases of Yeast
Until about 1957 the L(+)-lactic dehydrogenase of aerobic cells was the only enzyme concerned with lactate oxidation known to occur in yeast. At that time, essentially simultaneously and independently, four laboratories discovered the existence of a second lactic dehydrogenase in yeast, which, in distinction to the L enzyme, occurred in anaerobic cells and reacted with ferricyanide but not cyto...
متن کاملThe Lactic Dehydrogenases of Yeast
The n-lactic cytochrome reductase of yeast, discovered some 4 years ago (5), is a zinc-flavoprot,ein present in the respiratory granules of aerobic yeast. Its substrate specificity is highly restricted in that it oxidizes only D( -)-lactate and n-a-hydroxybutyrate and reduces only phenazine methosulfate and cytochrome c (6, 7). In these respects and many others, it differs from the L(+)-lactic ...
متن کاملLactic Dehydrogenases of Pseudomonas Natriegens.
Walker, Hazel (University of Georgia, Athens), and R. G. Eagon. Lactic dehydrogenases of Pseudomonas natriegens. J. Bacteriol. 88:25-30. 1964.-Lactic dehydrogenases specific for d- and l-lactate were demonstrated in Pseudomonas natriegens. The l-lactic dehydrogenase showed considerable heat stability, and 40% of the activity remained in extracts after heating at 60 C for 10 min. An essential th...
