EC Tree
IUBMB Comments
This enzyme is a multi-domain polypeptide that catalyses three different activities - a biotin carboxyl-carrier protein (BCCP), a biotin carboxylase that catalyses the transfer of a carboxyl group from hydrogencarbonate to the biotin molecule carried by the carrier protein, and the transfer of the carboxyl group from biotin to acetyl-CoA, forming malonyl-CoA. In some organisms these activities are catalysed by separate enzymes (see EC 6.3.4.14, biotin carboxylase, and EC 2.1.3.15, acetyl-CoA carboxytransferase). The carboxylation of the carrier protein requires ATP, while the transfer of the carboxyl group to acetyl-CoA does not.

LITERATURE
biofuel production
-
Saccharomyces cerevisiae is engineered to produce fatty acid-derived biofuels and chemicals from simple sugars. All three primary genes involved in fatty acid biosynthesis, namely ACC1, FAS1 and FAS2 are overexpressed. Combining this metabolic engineering strategy with terminal converting enzymes (diacylglycerol-acyltransferase,fatty acyl-CoA thioesterase,fatty acyl-CoA reductase, and wax ester synthase for TAG,fatty acid, fatty alcohol and FAEE production, respectively) improves the production levels of all biofuel molecules and chemicals, Saccharomyces cerevisiae provides a compelling platform for a scalable, controllable and economic route to biofuel molecules and chemicals
drug development
-
the structure of the enzyme's active site can be used for drug discovery
synthesis
-
in yeast engineered to produce the polyketide 6-methylsalisylic acid (6-MSA), both 6-MSA and native fatty acid levels increase by 3fold in presence of mutant S1157A which is not deactivated when glucose is depleted
