Multienzyme complex fatty acid synthase
Web26 oct. 2004 · Human fatty acid synthase is a large homodimeric multifunctional enzyme that synthesizes palmitic acid. The unique carboxyl terminal thioesterase domain of fatty acid synthase hydrolyzes the growing fatty acid chain and plays a critical role in regulating the chain length of fatty acid released. Web13 apr. 2007 · Although in some bacterial multifunctional enzymes, such as the fatty acid β-oxidation complex ( 15 ), individual domains have been observed to form more tangential interactions, the expansion segments in fungal FAS stably integrate the catalytic domains into the complex.
