Entry
EC 3.1.1.76                 Enzyme                                 

Name
poly(3-hydroxyoctanoate) depolymerase;
PHO depolymerase;
poly(3HO) depolymerase;
poly[(R)-hydroxyalkanoic acid] depolymerase;
poly(HA) depolymerase;
poly(HAMCL) depolymerase;
poly[(R)-3-hydroxyoctanoate] hydrolase
Class
Hydrolases;
Acting on ester bonds;
Carboxylic-ester hydrolases
BRITE hierarchy
Sysname
poly{oxycarbonyl[(R)-2-pentylethylene]} hydrolase
Reaction(IUBMB)
Hydrolyses the polyester poly{oxycarbonyl[(R)-2-pentylethylene]} to oligomers [RN:R05796]
Reaction(KEGG)
Comment
The main product after prolonged incubation is the dimer [3]. 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.
