ENZYMIC-SYNTHESIS OF GLUTAMIC-ACID GAMMA-SEMIALDEHYDE (DELTA-1-PYRROLINE-5-CARBOXYLATE) AND N-ACETYL-L-GLUTAMIC ACID GAMMA-SEMIALDEHYDE - ISOLATION AND CHARACTERIZATION OF THEIR 2,4-DINITROPHENYLHYDRAZONES

A protocol is given for the synthesis, by a simple enzyme preparation, of the l-isomers of glutamic acid γ-semialdehyde and N-acetylglutamic acid γ-semialdehyde. The isolation and physical and chemical properties of these products as the 2,4-dinitrophenylhydrazone derivatives are described. Spectral characteristics, NMR, ir, and visible, and melting points for these compounds are given. © 1979.
