CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00504};
CC       Note=Binds 2 manganese ions per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_00504};
CC   -!- SUBUNIT: Homohexamer. {ECO:0000255|HAMAP-Rule:MF_00504}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00504}.
CC   -!- SIMILARITY: Belongs to the peptidase M17 family. {ECO:0000255|HAMAP-
CC       Rule:MF_00504}.
