Product Description

Specificity:

Blood CO2 transport and excretion is largely dependent on the rapid catalysis of the CO2 reactions within the erythrocyte by CA (Tufts et al. 2003). Bovine CA reversibly hydrates alkyl pyruvates and it exhibits hydratase activity toward a wide variety of substrates (Pocker et al. 1974, and Wells et al. 1975).
