The stereospecificity of nicotinamide-adenine dinucleotide-dependent oxidoreductases from plants.
1. The stereospecificity of 20 enzymes from plants is reported. 2. The stereospecificity of all known forms of malate dehydrogenase in plants and animals has been shown to be A-specific. 3. The generalization that ;the stereospecificity of a particular reaction is independent of the source of the enzyme' is confirmed for a total of 12 plant enzymes. 4. A new generalization is proposed: ;When a metabolic sequence involves consecutive nicotinamide-adenine dinucleotide-dependent reactions, the dehydrogenases have the same stereospecificity.'
