CC   -!- FUNCTION: The physiological role of BioH is to remove the methyl group
CC       introduced by BioC when the pimeloyl moiety is complete. It allows to
CC       synthesize pimeloyl-ACP via the fatty acid synthetic pathway through
CC       the hydrolysis of the ester bonds of pimeloyl-ACP esters.
CC       {ECO:0000255|HAMAP-Rule:MF_01260}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=6-carboxyhexanoyl-[ACP] methyl ester + H2O = 6-
CC         carboxyhexanoyl-[ACP] + H(+) + methanol; Xref=Rhea:RHEA:42700,

CC         Rule:MF_01260};
CC   -!- PATHWAY: Cofactor biosynthesis; biotin biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_01260}.
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_01260}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01260}.
CC   -!- SIMILARITY: Belongs to the AB hydrolase superfamily. Carboxylesterase
CC       BioH family. {ECO:0000255|HAMAP-Rule:MF_01260}.
CC   -!- SEQUENCE CAUTION:
