S-acyl fatty acid synthase thioesterase, medium chain (EC 3.1.2.14) (Oleoyl-ACP hydrolase) (Thioesterase II) (Thioesterase domain- containing protein 1); In fatty acid biosynthesis chain termination and release of the free fatty acid product is achieved by hydrolysis of the thio ester by a thioesterase I, a component of the fatty acid synthetase complex. The chain length of the released fatty acid is usually C16. However, in the mammary glands of non-ruminant mammals, and in the uropygial gland of certain waterfowl there exists a second thioesterase which releases medium-chain length f [...] (318 aa)
