General annotation (Comments)

Function

Catalyzes the rate-limiting reaction in the mitochondrial fatty acid synthesis (FAS) type II pathway. Responsible for the production of the mitochondrial malonyl-CoA, used for the biosynthesis of the cofactor lipoic acid. This protein carries three functions: biotin carboxyl carrier protein, biotin carboxylase, and carboxyltransferase By similarity.

Catalytic activity

ATP + acetyl-CoA + HCO3- = ADP + phosphate + malonyl-CoA.

ATP + biotin-[carboxyl-carrier-protein] + CO2 = ADP + phosphate + carboxy-biotin-[carboxyl-carrier-protein].

Cofactor

Biotin By similarity.

Pathway

Lipid metabolism; malonyl-CoA biosynthesis; malonyl-CoA from acetyl-CoA: step 1/1.

Subcellular location

Mitochondrion By similarity.

Sequence similarities

Contains 1 ATP-grasp domain.

Contains 1 biotin carboxylation domain.

Contains 1 biotinyl-binding domain.

Contains 1 carboxyltransferase domain.

Caution

The reading frame from which this protein is translated has no Met initiation codon near to the 5'-end. However, it is not a pseudogene. It has been shown that at least 72 residues upstream of the first in-frame start codon (Met-151) are required for function and proper subcellular location. May be translated by means of alternative initiation codon usage, programmed translational frame shifting, or mRNA editing.

Sequence caution

The sequence EDV11698.1 differs from that shown. Reason: Erroneous initiation.
