CC -!- FUNCTION: Catalyzes the conversion of S-adenosyl-L-methionine (SAM) to
CC carboxy-S-adenosyl-L-methionine (Cx-SAM). {ECO:0000256|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:0000256|HAMAP-
CC Rule:MF_01589};
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. Cx-SAM synthase family. {ECO:0000256|HAMAP-Rule:MF_01589}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01589}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
