FAS enzymes
names and functions of enzymes present in E. coli fatty acid synthase complex
Question | Answer |
---|---|
Acyl carrier protein (ACP) | carries acyl groups in thioester linkage |
Acetyl-CoA-ACP transacetylase(AT) | transfers acyl group from CoA to Cys residue of KS |
beta-Ketoacyl-ACP synthase(KS) | condenses acyl and malonyl groups (at least 3 isozymes) |
Malonyl-CoA-ACP transferase(MT) | transfers malonyl group from CoA to ACP |
beta-Ketoacyl-ACP reductase(KR) | reduces beta-keto group to beta-hydroxyl group |
beta-hydroxyacyl-ACP dehyratase(HD) | removes H2O from beta-hydroxyacyl-ACP, creating double bond |
Enoyl-ACP reductase(ER) | reduces double bond, forming saturated acyl-ACP |
