Functions of malonate decarboxylase subunits from Pseudomonas putida.

Malonate decarboxylase from Pseudomonasputida is composed of five subunits, alpha, beta, gamma, delta, and epsilon. Two subunits, delta and epsilon, have been identified as an acyl-carrier protein (ACP) and malonyl-CoA:ACP transacylase, respectively. Functions of the other three subunits have not been identified, because recombinant subunits expressed in Escherichia coi formed inclusion bodies.
