Comments [?]

Function 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.
Catalytic activity RHEA:10172: (3R)-hydroxybutanoate dimer + H2O = 2 (R)-3-hydroxybutanoate + H(+)
EC 3.1.1.22
Pathway Lipid metabolism; butanoate metabolism.
case <Feature:Signal==1>
Subcellular location Secreted.
end case
Similarity Belongs to the D-(-)-3-hydroxybutyrate oligomer hydrolase family.
