DESCRIPTION

Also known as APCB_AROAE, apc2, apcB. Catalyzes the carboxylation of acetophenone to form 3-oxo-3-phenylpropanoate (benzoylacetate) in the anaerobic catabolism of ethylbenzene. Also carboxylates propiophenone at the same rate and 4-acetyl-pyridine at lower rates. Acetophenone carboxylase consists of five subunits; a heterooctameric subcomplex of two alpha (Apc1), two beta (Apc2), two gamma (Apc3) and two delta (Apc4) subunits assembles with the epsilon (Apc5) subunit in an unknown stoichiometry.
