Cofactor	COFACTOR: Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence={ECO:0000269|PubMed:10537112}; Note=Binds 1 Ca(2+) ion per monomer. In the dimeric form the Ca(2+) is bound by different amino acids with binding of each Ca(2+) shared with ligands coming from each monomer (Arg-167 and Ser-172 from 1 monomer, Ser-126 of the other). The Ca(2+) ion may have a role in catalysis. {ECO:0000269|PubMed:10537112};
Active site	ACT_SITE 162 162 Proton acceptor. {ECO:0000305}.; ACT_SITE 164 164 Nucleophile. {ECO:0000269|PubMed:2040286}.
