CC carboxy-S-adenosyl-L-methionine + H2O; Xref=Rhea:RHEA:51692,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:18005, ChEBI:CHEBI:29934,
CC ChEBI:CHEBI:59789, ChEBI:CHEBI:134278; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01589};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01589}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. Cx-SAM synthase family. {ECO:0000255|HAMAP-Rule:MF_01589}.
