<prompt> Enzyme in fatty acid synthase complex that has pantothenic acid as coenzyme:Acetyl transacylase.Thioesterase.Enoyl reductase.Acyl carrier protein.  <response>: In eukaryotic cells, including man, the fatty acid synthase exists as a dimmer with two identical units. Each monomer possesses the activities of seven different enzymes and an acyl carrier protein ACP bound to 4 phosphopentethiene.
