Because PHB is a material rather than a single protein, the genetic construct is designed to express the three enzymes of the PHB biosynthesis pathway: PhaA — acetyl-CoA acetyltransferase PhaB — acetoacetyl-CoA reductase PhaC — PHB synthase Together, these enzymes convert acetyl-CoA into PHB. The three-enzyme pathway is also associated with PHB production in Methylocystis and other PHB-producing bacteria.Hugoen
