D-Alanine and several D,L-amino acids were administered to pea seedlings to investigate formation of D-amino acid conjugates. The N-malonylation occurred with all the D-amino acids administered. D-Alanine was specifically converted to additional .gamma.-L-glutamyl conjugate and this .gamma.-L-glutamylation predominated over the N-malonylation with respect to D-alanine. The other D-amino acids tested were slightly or scarcely utilized for .gamma.-L-glutamylation. Evidently, 2 systems exist for formation of D-amino acid conjugates in pea seedlings, N-malonylation of common D-amino acids and .gamma.-L-glutamylation highly specific to D-alanine.
