Rs. Gupta et al., SOME ENZYMES OF GLUCONEOGENESIS IN VARIOUS FRACTIONS OF SARCOCYSTS OFSARCOCYSTIS-FUSIFORMIS OF BUFFALO (BUBALUS-BUBALIS), Veterinary parasitology, 52(1-2), 1994, pp. 145-149
A biochemical study was conducted to assess the relative presence of s
ome enzymes of gluconeogenesis in various fractions-the cyst wall, cys
t fluid and zoites-of sarcocysts of Sarcocystis fusiformis obtained fr
om the oesophageal muscles of naturally infected Indian water buffalo
(Bubalus bubalis). The activities of fructose 1,6-diphosphatase and ma
lic enzyme were beyond detectable limits. Phosphoenol pyruvate carboxy
kinase (PEPCK) activity was maximally present in the zoites, whereas g
lucose 6-phosphatase activity was highest in the cyst wall. PEPCK seem
ed to play a crucial role in carbon dioxide fixation metabolism.
