Acetyl-CoA carboxyltransferase subunit beta

Usage and Biology

The acetyl-CoA carboxylase subunit beta is part of the acetyl-CoA carboxylase ACC, which is the major regulator for fatty acid biosynthesis in E. coli. In this complex it forms an α₂β₂ heterotetramer with the acetyl-CoA carboxylase subunit alpha encoded by the accA gene.¹ This tetramer catalyzes the reaction of acetyl-CoA to malonyl-CoA by transferring a carboxyl group from carboxybiotin.²

The acetyl-CoA carboxyltransferase was used in our myristic acid synthesis module, BBa_K2588022.
