Temperature and pH effects on the total white muscle LDH of Oreochromis niloticus (Pisces: Cichlidae).
The total lactate dehydrogenase enzyme activity of white muscle from O. niloticus shows positive thermal modulation. There is a tendency towards conservation of binding capacity for substrate at physiologically changing pH conditions. Inhibition by excess pyruvate is influenced by temperature and pH, but this phenomenon is not considered to be important in anaerobic glycolysis.
