FIG. 3.
Initiation (A) and elongation (B) phases of fatty acid biosynthesis. Initiation: accA, carboxyltransferase (α subunit); accD, carboxyltransferase (β subunit); fadA, thiolase; fabD, malonyl-CoA:ACP transacylase. Elongation: fabF, 3-ketoacyl-ACP synthase; fabH, 3-ketoacyl-ACP synthase; fabI, enoyl-ACP reductase; fabG, 3-ketoacyl-ACP-reductase; fabZ, (3R)-hydroxymyristoyl-ACP dehydratase.
