Protein

Acetyl-coenzyme A carboxylase carboxyl transferase subunit beta, chloroplastic

Gene

accD

Organism
Ceratophyllum demersum (Rigid hornwort) (Coontail)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Component of the acetyl coenzyme A carboxylase (ACC) complex. Biotin carboxylase (BC) catalyzes the carboxylation of biotin on its carrier protein (BCCP) and then the CO2 group is transferred by the transcarboxylase to acetyl-CoA to form malonyl-CoA.UniRule annotation

Catalytic activityi

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

Cofactori

Zn2+UniRule annotationNote: Binds 1 zinc ion per subunit.UniRule annotation

Pathwayi: malonyl-CoA biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes malonyl-CoA from acetyl-CoA.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Acetyl-coenzyme A carboxylase carboxyl transferase subunit beta, chloroplastic (accD), Acetyl-coenzyme A carboxylase carboxyl transferase subunit beta, chloroplastic (accD)
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.
