OX NCBI_TaxID=9925; RN [1] RP NUCLEOTIDE SEQUENCE. RX PubMed=3922356; DOI=10.1042/bj2270021; RA Mikkelsen J., Hoejrup P., Rasmussen M.M., Roepstorff P., Knudsen J.; RT "Amino acid sequence around the active-site serine residue in the RT acyltransferase domain of goat mammary fatty acid synthetase."; RL Biochem. J. 227:21-27(1985). CC -!- FUNCTION: Fatty acid synthetase catalyzes the formation of long-chain CC fatty acids from acetyl-CoA, malonyl-CoA and NADPH. This CC multifunctional protein has 7 catalytic activities as an acyl carrier CC protein. CC -!- FUNCTION: This fragment is from the acyltransferase domain of the fatty CC acid synthetase. CC -!- CATALYTIC ACTIVITY: CC Reaction=acetyl-CoA + 2n H(+) + n malonyl-CoA + 2n NADPH = a long-chain CC fatty acid + n CO2 + (n+1) CoA + 2n NADP(+); Xref=Rhea:RHEA:14993, CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:57287, CC ChEBI:CHEBI:57288, ChEBI:CHEBI:57384, ChEBI:CHEBI:57560, CC ChEBI:CHEBI:57783, ChEBI:CHEBI:58349; EC=2.3.1.85; CC -!- SUBUNIT: Homodimer which is arranged in a head to tail fashion (By CC similarity). Interacts with CEACAM1; this interaction is insulin and CC phosphorylation-dependent; reduces fatty-acid synthase activity (By CC similarity). {ECO:0000250|UniProtKB:P12785, CC ECO:0000250|UniProtKB:P49327}.
