CC -!- FUNCTION: Catalyzes the epimerization of trans-4-hydroxy-L-proline
CC (t4LHyp) to cis-4-hydroxy-D-proline (c4DHyp). Is likely involved in a
CC degradation pathway that converts t4LHyp to alpha-ketoglutarate. Can
CC also catalyze the epimerization of trans-3-hydroxy-L-proline (t3LHyp)
CC to cis-3-hydroxy-D-proline (c3DHyp), albeit with 19-fold lower
CC efficiency. Displays no proline racemase activity.
CC {ECO:0000269|PubMed:24980702}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=trans-4-hydroxy-L-proline = cis-4-hydroxy-D-proline;
CC Xref=Rhea:RHEA:21152, ChEBI:CHEBI:57690, ChEBI:CHEBI:58375;
CC EC=5.1.1.8; Evidence={ECO:0000269|PubMed:24980702};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=6.8 mM for trans-4-hydroxy-L-proline
CC {ECO:0000269|PubMed:24980702};
CC KM=57 mM for trans-3-hydroxy-L-proline {ECO:0000269|PubMed:24980702};
CC Note=kcat is 70 sec(-1) for t4LHyp epimerization. kcat is 30 sec(-1)
CC for t3LHyp epimerization. {ECO:0000269|PubMed:24980702};
CC -!- SIMILARITY: Belongs to the proline racemase family. {ECO:0000305}.
