Deamination of Serine
In an investigation of transamination reactions between pyridoxal and amino acids at 100” (2) serine was found to behave anomalously, apparently being deaminated to pyruvic acid with little change in pyridoxal concentration. Although serine is known to be deaminated by hot concentrated alkalies (3) and acids (4), such a non-enzymatic reaction in the pH range near neutrality has not been reporte...

متن کاملDEAMINATION OF SERINE II. D-SERINE DEHYDRASE, A VITAMIN Bs ENZYME FROM ESCHERICHIA COLP
Non-enzymatic deamination of serine and cysteine is catalyzed by pyridoxal and certain metal salts at 100” (2). This finding suggested that pyridoxal phosphate might be involved in the enzymatic deamination of these amino acids. Vitamin B, has already been implicated in the desulfhydration of cysteine by rat liver (3) and of cysteine and homocysteine by bacteria (4). Several similarities of cys...
