CC   -!- FUNCTION: Catalyzes the conversion of S-adenosyl-L-methionine (SAM) to
CC       carboxy-S-adenosyl-L-methionine (Cx-SAM). {ECO:0000255|HAMAP-
CC       Rule:MF_01589}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=prephenate + S-adenosyl-L-methionine = 3-phenylpyruvate +
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}.
