STUDIES ON LYSINE FERMENTATION II.

α, ε-DIAMINOPIMELIC ACID AND ITS DECARBOXYLASE IN LYSINE PRODUCING STRAIN AND PARENT STRAIN

Abstract

α, ε-Diaminopimelic acid (DAPA) and DAPA-decarboxylase were found in lysine requiring strains and a parent strain of Micrococcus glutamicus. With acetone dried cell, DAPA was decarboxylated quantitatively to lysine, while DAPA was not decarboxylated to lysine with intact cell.
Lysine producing strain (M. 801) scarcely decomposed lysine.
A biosynthetic pathway of lysine via DAPA was discussed.
