Protein

Biotin carboxylase 1

Gene

accC1

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Protein inferred from homologyi

Functioni

This protein is a component of the acetyl coenzyme A carboxylase complex; first, biotin carboxylase catalyzes the carboxylation of the carrier protein and then the transcarboxylase transfers the carboxyl group to form malonyl-CoA.By similarity

Catalytic activityi

ATP + biotin-[carboxyl-carrier-protein] + HCO3- = ADP + phosphate + carboxy-biotin-[carboxyl-carrier-protein].
ATP + acetyl-CoA + HCO3- = ADP + phosphate + malonyl-CoA.

Pathwayi: malonyl-CoA biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes malonyl-CoA from acetyl-CoA.
Proteins known to be involved in this subpathway in this organism are:
  1. Biotin carboxylase 2 (accC2), Acetyl-coenzyme A carboxylase carboxyl transferase subunit beta (accD), Biotin carboxylase 1 (accC1), Acetyl-coenzyme A carboxylase carboxyl transferase subunit alpha (accA)
This subpathway is part of the pathway malonyl-CoA biosynthesis, which is itself part of Lipid metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes malonyl-CoA from acetyl-CoA, the pathway malonyl-CoA biosynthesis and in Lipid metabolism.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
