What is β-decarboxylation of l-aspartic acid: A metal chelate-catalyzed reaction about?
&decarboxylation of L-aspartic acid was observed in the system, pyridoxal: L-aspartic acid:aluminum(III), 1 I 100. -1 when heated at 80" for three hours. This reaction was followed by electronic spectroscopy and showed quantitative conversion of pyridoxal to pyridoxamine indicating decarboxylation of the ketimine. a-Methyl-l-aspartic acid was not decarboxylated indicating the presence of the a-proton and prior transamination as requirements for decarboxylation. When pyridoxamine and oxalo-Zpropionic acid were reacted at pD 4.60, product analysis by nmr showed the presence of pyridoxamine and o-ketobutyric acid, indica;ing hydrolysis of the decarboxylated ketimine. Decarboxylation was fast compared to spontaneous decarboxylation. A mechanism is proposed for non-enzymatic decarboxylation and the previously suggested mechanism for the inactivation of the enzyme aspartate p-decarboxylase is discussed\_
