The specificity of coupled esterification of phosphate in muscle

Abstract
Further evidence has been obtained showing that in muscle extract oxidoreductions involving glyceraldehyde are not accompanied by coupled esterification of phosphate. The oxidore-duction between triosephosphate and pyruvate has been separated into its 2 constituent reactions. The oxidation of triosephosphate to phosphoglyceric acid by coenzyme is accompanied by esterification; the oxidation of reduced coenzyme thus formed by pyruvate is not accompanied by esterification. Adenylic acid has an activating effect on oxidoreduction involving triosephosphate, but an inhibitory effect on oxidoreduction involving glyceraldehyde.
