Enzyme Commission Primary Name: poly(3-hydroxybutyrate) depolymerase
Enzyme Commission Synonyms: PHB depolymerase, poly(3HB) depolymerase, poly[(R)-hydroxyalkanoic acid] depolymerase, poly(HA) depolymerase, poly(HASCL) depolymerase, poly[(R)-3-hydroxybutyrate] hydrolase
Standard Gibbs Free Energy (ΔrG'° in kcal/mol): -13.819489 [Latendresse13]
Enzyme Commission Summary:
Reaction also occurs with esters of other short-chain-length (C(1)-C(5)) hydroxyalkanoic acids (HA). There are two types of polymers: native (intracellular) granules are amorphous and have an intact surface layer; denatured (extracellular) granules either have no surface layer or a damaged surface layer and are partially crystalline.
