CC -!- FUNCTION: Splits dipeptides with a prolyl residue in the C-terminal
CC position. {ECO:0000255|HAMAP-Rule:MF_01279}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of Xaa-|-Pro dipeptides. Also acts on aminoacyl-
CC hydroxyproline analogs. No action on Pro-|-Pro.; EC=3.4.13.9;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01279};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01279};
CC Note=Binds 2 manganese ions per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_01279};
CC -!- SIMILARITY: Belongs to the peptidase M24B family. Bacterial-type
CC prolidase subfamily. {ECO:0000255|HAMAP-Rule:MF_01279}.
