Some enzymes of gluconeogenesis in various fractions of sarcocysts of Sarcocystis fusiformis of buffalo (Bubalus bubalis).
A biochemical study was conducted to assess the relative presence of some enzymes of gluconeogenesis in various fractions--the cyst wall, cyst fluid and zoites--of sarcocysts of Sarcocystis fusiformis obtained from the oesophageal muscles of naturally infected Indian water buffalo (Bubalus bubalis). The activities of fructose 1,6-diphosphatase and malic enzyme were beyond detectable limits. Phosphoenol pyruvate carboxykinase (PEPCK) activity was maximally present in the zoites, whereas glucose 6-phosphatase activity was highest in the cyst wall. PEPCK seemed to play a crucial role in carbon dioxide fixation metabolism.
