UniProt functional annotation for P53554

UniProt code: P53554.

Organism: Bacillus subtilis (strain 168).
Taxonomy: Bacteria; Firmicutes; Bacilli; Bacillales; Bacillaceae; Bacillus.
 
Function: Catalyzes the C-C bond cleavage of fatty acid linked to acyl carrier protein (ACP) to generate pimelic acid for biotin biosynthesis. It has high affinity for long-chain fatty acids with the greatest affinity for myristic acid. {ECO:0000269|PubMed:11368323, ECO:0000269|PubMed:8763940}.
 
Catalytic activity: Reaction=a C2-C8-saturated long-chain fatty acyl-[ACP] + 3 O2 + 2 reduced [flavodoxin] = 6-carboxyhexanoyl-[ACP] + a fatty aldehyde + 3 H(+) + 3 H2O + 2 oxidized [flavodoxin]; Xref=Rhea:RHEA:52852, Rhea:RHEA-COMP:9955, Rhea:RHEA-COMP:10622, Rhea:RHEA-COMP:10623, Rhea:RHEA-COMP:13382, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379, ChEBI:CHEBI:35746, ChEBI:CHEBI:57618, ChEBI:CHEBI:58210, ChEBI:CHEBI:78846, ChEBI:CHEBI:136878; EC=1.14.14.46; Evidence={ECO:0000269|PubMed:11368323};
Cofactor: Name=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000269|PubMed:18838690}; Note=Binds 1 heme group covalently per subunit. {ECO:0000269|PubMed:18838690};
Pathway: Cofactor biosynthesis; biotin biosynthesis.
Mass spectrometry: Mass=44732; Method=Electrospray; Evidence={ECO:0000269|PubMed:11472016};
Mass spectrometry: Mass=45348; Method=Electrospray; Evidence={ECO:0000269|PubMed:11368323};
Similarity: Belongs to the cytochrome P450 family. {ECO:0000305}.
