Pimelyl (acyl carrier protein) methyl ester esterase

Pimelyl-(acyl-carrier protein) methyl ester esterase (EC 3.1.1.85, BioH) is an enzyme with systematic name pimelyl-(acyl-carrier protein) methyl ester hydrolase. This enzyme catalyses the following chemical reaction

pimelyl-[acyl-carrier protein] methyl ester + H₂O ⇌ pimelyl-[acyl-carrier protein] + methanol

This enzyme takes part in biotin biosynthesis in Gram-negative bacteria.
