title: Stereospecificity of hydrogen transfer by phosphoglycerate dehydrogenase.
abstract: Phosphoglycerate dehydrogenase (EC 1.1.1.95) has been shown to be A site specific in its hydrogen transfer capacity unlike other dehydrogenases which use phosphorylated substrates. The experiments have been carried out using a coupled assay system with yeast alcohol dehydrogenase. The specific activity measurements of the reaction products indicate the possible influence of an isotope effect on this system.
