It works downstream of poly(3-hydroxybutyrate) depolymerase, CC hydrolyzing D(-)-3-hydroxybutyrate oligomers of various length (3HB- CC oligomers) into 3HB-monomers. CC -!- CATALYTIC ACTIVITY: CC Reaction=(3R)-hydroxybutanoate dimer + H2O = 2 (R)-3-hydroxybutanoate + CC H(+); Xref=Rhea:RHEA:10172, ChEBI:CHEBI:10979, ChEBI:CHEBI:10983, CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378; EC=3.1.1.22; CC -!- PATHWAY: Lipid metabolism; butanoate metabolism. case CC -!- SUBCELLULAR LOCATION: Secreted. end case CC -!- SIMILARITY: Belongs to the D-(-)-3-hydroxybutyrate oligomer hydrolase CC family.
