IUBMB Comments
The main product after prolonged incubation is the dimer . Besides hydrolysing polymers of 3-hydroxyoctanoic acid, the enzyme also hydrolyses other polymers derived from medium-chain-length (C6-C12) hydroxyalkanoic acids and copolymers of mixtures of these. It also hydrolyses p-nitrophenyl esters of fatty acids. Polymers of short-chain-length hydroxyalkanoic acids such as poly[(R)-3-hydroxybutanoic acid] and poly[(R)-3-hydroxypentanoic acid] are not hydrolysed.
