Probable polyketide synthase. Binds 1 phosphopantetheine covalently. Modular protein that is responsible for the completion of one condensation-processing cycle. The beta-ketoacyl synthase region is responsible for the actual condensation reaction while the acyl/malonyl transferase region is responsible for incorporating carboxylic acids units onto an acyl carrier protein (ACP) domain (By similarity). Encoded by one of the numerous copies of polyketide synthase genes.
