Abstract

The stoichiometry of the oxidative phosphorylation of glutamic acid 5-semialdehyde by gamma-glutamyl phosphate reductase (glutamate semialdehyde dehydrogenase) has been established. Equimolar amounts of NADP+ and L-glutamic acid 5-semialdehyde are consumed and equimolar amounts of 5-oxiopyrroilidine-2-carboxylic acid and NADPH are formed. The end-product of the reaction is demonstrated to be 5-oxopyrrolidine-2-carboxylic acid, probably arising from the true end-product gamma-glutamyl phosphate.
