CC ChEBI:CHEBI:74411, ChEBI:CHEBI:82852; EC=3.5.4.33;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00972};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00972};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00972};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00972}.
