to achieve decarboxylation of malonate, the key reaction in the decomposition of this compound, the substrate must be activated by the malonate decarboxylase to a malonyl thio-enzyme ester involving an activation module that comprises the acetylation of a specific thiol group of an acyl carrier protein, ACP, and the transfer of the ACP moiety to malonate, yielding malonyl-S-ACP and acetate. The malonyl-S-ACP is subsequently decarboxylated with regeneration of the acetyl-ACP. Malonate decarboxylation pathway, overview |
