UniProt functional annotation for P43873 | ||
|
|
|
|
|
|
||
| UniProt code: P43873. |
|
||
| Organism: | |
Haemophilus influenzae (strain ATCC 51907 / DSM 11121 / KW20 / Rd). |
| Taxonomy: | |
Bacteria; Proteobacteria; Gammaproteobacteria; Pasteurellales; Pasteurellaceae; Haemophilus. |
|
||
|
||
| Function: | |
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. {ECO:0000250}. |
|

| Catalytic activity: | |
Reaction=ATP + hydrogencarbonate + N(6)-biotinyl-L-lysyl-[protein] = ADP + H(+) + N(6)-carboxybiotinyl-L-lysyl-[protein] + phosphate; Xref=Rhea:RHEA:13501, Rhea:RHEA-COMP:10505, Rhea:RHEA-COMP:10506, ChEBI:CHEBI:15378, ChEBI:CHEBI:17544, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:83144, ChEBI:CHEBI:83145, ChEBI:CHEBI:456216; EC=6.3.4.14; |
| Catalytic activity: | |
Reaction=acetyl-CoA + ATP + hydrogencarbonate = ADP + H(+) + malonyl- CoA + phosphate; Xref=Rhea:RHEA:11308, ChEBI:CHEBI:15378, ChEBI:CHEBI:17544, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:57288, ChEBI:CHEBI:57384, ChEBI:CHEBI:456216; EC=6.4.1.2; |
| Pathway: | |
Lipid metabolism; malonyl-CoA biosynthesis; malonyl-CoA from acetyl-CoA: step 1/1. |
| Subunit: | |
Acetyl-CoA carboxylase is a heterohexamer of biotin carboxyl carrier protein, biotin carboxylase and the two subunits of carboxyl transferase in a 2:2 complex. {ECO:0000250}. |
