Enzymatic Formation of Aminomalonic Acid from Ketomalonic Acid

Article metrics


RECENT work in this laboratory demonstrated the occurrence of a new enzyme, aminomalonic acid decarboxylase, in the posterior silk-gland of silkworm and in rat liver1. The fact that this enzyme was first observed in silkworm, which has a remarkably high activity of glycine synthesis2, seems to suggest a physiological significance of the enzyme in the biosynthesis of glycine, although natural occurrence of this amino-acid has hitherto not been reported.
