CC -!- FUNCTION: Catalyzes the SAM-dependent triple methylation of the alpha-
CC amino group of histidine to form hercynine, a step in the biosynthesis
CC pathway of ergothioneine. {ECO:0000256|HAMAP-Rule:MF_02037}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-histidine + 3 S-adenosyl-L-methionine = 3 H(+) + hercynine +
CC 3 S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:38471, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:15781, ChEBI:CHEBI:57595, ChEBI:CHEBI:57856,
CC ChEBI:CHEBI:59789; EC=2.1.1.44; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_02037};
CC -!- PATHWAY: Amino-acid biosynthesis; ergothioneine biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_02037}.
CC -!- SUBUNIT: Monomer. {ECO:0000256|HAMAP-Rule:MF_02037}.
CC -!- SIMILARITY: Belongs to the methyltransferase superfamily. EgtD family.
CC {ECO:0000256|HAMAP-Rule:MF_02037}.
