A cluster of four genes was identified in the Rhodobacter capsulatus genome that is involved in PHA metabolism. These genes encode the PHA granule-associated protein (pha2), the regulator for granule formation (pha1), the PHA synthase (phaC) and the PHA depolymerase (orfX). Two other genes, namely those encoding β-ketothiolase (phaA) and acetoacetyl-CoA reductase (phaB), are not linked to this cluster.
