Protein

D-(-)-3-hydroxybutyrate oligomer hydrolase

Gene

Bpro_4732

Organism
Polaromonas sp. (strain JS666 / ATCC BAA-500)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Participates in the degradation of poly-3-hydroxybutyrate (PHB). It works downstream of poly(3-hydroxybutyrate) depolymerase, hydrolyzing D--3-hydroxybutyrate oligomers of various length (3HB-oligomers) into 3HB-monomers.UniRule annotation

Catalytic activityi

(R)-3-((R)-3-hydroxybutanoyloxy)butanoate + H2O = 2 (R)-3-hydroxybutanoate.UniRule annotation

Pathwayi: butanoate metabolism

This protein is involved in the pathway butanoate metabolism, which is part of Lipid metabolism.UniRule annotation
