EC 3.1.1.85 Details

show Brenda entry

EC number

3.1.1.85

Accepted name

pimelyl-[acyl-carrier protein] methyl ester esterase

Reaction

pimeloyl-[acyl-carrier protein] methyl ester + H₂O = pimeloyl-[acyl-carrier protein] + methanol

Other name(s)

BioH

Systematic name

pimeloyl-[acyl-carrier protein] methyl ester hydrolase

Comment

Involved in biotin biosynthesis in Gram-negative bacteria. The enzyme exhibits carboxylesterase activity, particularly toward substrates with short acyl chains [1,2]. Even though the enzyme can interact with coenzyme A thioesters [3], the in vivo role of the enzyme is to hydrolyse the methyl ester of pimeloyl-[acyl carrier protein], terminating the part of the biotin biosynthesis pathway that is catalysed by the fatty acid elongation enzymes [4].
