The effect of temperature on catalytic function of glyceraldehyde-3-phosphate dehydrogenase from muscle of pig and carp Cyprinus carpio.
1. The temperature dependence of the kinetics of glyceraldehyde-3-phosphate dehydrogenase from white muscle of carp and skeletal muscle of pig was examined. 2. The Km values of carp muscle enzyme were stable over the temperature range 5-35 degrees C, but increased for pig muscle enzyme with increasing temperature. 3. The Arrhenius plot for pig muscle enzyme is linear but non-linear for carp muscle enzyme. 4. The differences indicate that glyceraldehyde-3-phosphate dehydrogenase from white carp muscle may contribute to the adaptive mechanism of carp to varied temperature conditions.
