Probable polyketide synthase (By similarity). May be involved in the process of cell migration. 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 and clustered as a quartet pks29/pks30/pks31/pks32 in chromosome 5.
