Purification and properties of XXXX dehydrogenase from potato tubers.

@entity2125 @entity28869 @entity1110 @entity5097 @entity855
1. A purification of @entity5097 dehydrogenase is described. 2. The final preparation is active with @entity2125 and @entity1110 and with a number of @entity28869 , but evidence is presented to support the view that a single enzyme is involved. 3. @entity2125 showed product inhibition, but at slightly acid pH values there was evidence of co-operative binding. 4. At acid pH values @entity855 was a potent inhibitor and appears to be an allosteric effector. At neutral or alkaline pH values @entity855 behaved as a weak competitive inhibitor. 5. The physiological significance of inhibition by @entity855 is discussed.
