CC   -!- FUNCTION: Allows intracellular utilization of 4-hydroxyproline, one of
CC       the major constituents of host collagen, by converting 4-hydroxy-L-
CC       proline to 4-hydroxy-D-proline, which can be further metabolized by
CC       intracellular 4-hydroxy-D-proline oxidases. Strong B-cell mitogen.
CC       Plays an important role in the regulation of intra- and extracellular
CC       amino acid pools, allowing the bacterium to profit from host precursors
CC       and enzymatic pathways (By similarity). {ECO:0000250}.
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;
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the proline racemase family. {ECO:0000305}.
