Malatdehydrogenase - Samer Taha

Malatdehydrogenase - Samer Taha

Electrophoretically homogeneous preparations of MDH (CF 1.1.1.37) from bacteria of the genus Sphaerotilus were obtained through multistep purification. A dimeric form of the enzyme (73 kDa) functions during organotrophic growth in S. natans D-380. The molecular weight of the MDH subunits was 35 kDa. Michaelis constants for oxaloacetate, malate, NAD+, NADH were determined. The effect of metal ions on the activity of malate dehydrogenase was also studied, and the temperature optimums for the forward..
