Protein: Acetyl-CoA carboxylase 1 (ACC1) (EC 6.4.1.2) (Acetyl-Coenzyme A carboxylase alpha) (ACC-alpha) (Q13085)
Organism: Homo sapiens (Human)
Function: Cytosolic enzyme that catalyzes the carboxylation of acetyl-CoA to malonyl-CoA, the first and rate-limiting step of de novo fatty acid biosynthesis. This is a 2 steps reaction starting with the ATP-dependent carboxylation of the biotin carried by the biotin carboxyl carrier (BCC) domain followed by the transfer of the carboxyl group from carboxylated biotin to acetyl-CoA.
Subcellular location: Cytoplasm, cytosol {ECO:0000250|UniProtKB:Q5SWU9}.
Interaction partners:
- Fatty acid synthase
- Breast cancer type 1 susceptibility protein

- Malonyl-CoA-acyl carrier protein transacylase, mitochondrial
- Acetyl-coenzyme A synthetase, cytoplasmic
- Malonyl-CoA decarboxylase, mitochondrial
