Identifier
BIOH
Protein name
RecName: Full=Pimeloyl-[acyl-carrier protein] methyl ester esterase;
EC=3.1.1.85;
AltName: Full=Biotin synthesis protein BioH;
AltName: Full=Carboxylesterase BioH;
Gene name
bioH

Comments [?]

Function The physiological role of BioH is to remove the methyl group introduced by BioC when the pimeloyl moiety is complete. It allows to synthesize pimeloyl-ACP via the fatty acid synthetic pathway through the hydrolysis of the ester bonds of pimeloyl-ACP esters (By similarity).
Catalytic activity Pimeloyl-[acyl-carrier protein] methyl ester + H(2)O = pimeloyl-[acyl-carrier protein] + methanol.
Pathway Cofactor biosynthesis; biotin biosynthesis.
Subunit Monomer (By similarity).
Subcellular location Cytoplasm (By similarity).
Similarity Belongs to the AB hydrolase superfamily. Carboxylesterase BioH family.
