CC   -!- FUNCTION: S-adenosyl-L-methionine-dependent methyltransferase that
CC       catalyzes the trimethylation of the amino group of the modified target
CC       histidine residue in translation elongation factor 2 (EF-2), to form an
CC       intermediate called diphthine. The three successive methylation
CC       reactions represent the second step of diphthamide biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_01084}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-[(3S)-amino-3-carboxypropyl]-L-histidyl-[translation
CC         elongation factor 2] + 3 S-adenosyl-L-methionine = diphthine-
CC         [translation elongation factor 2] + 3 H(+) + 3 S-adenosyl-L-
CC         homocysteine; Xref=Rhea:RHEA:36415, Rhea:RHEA-COMP:9749, Rhea:RHEA-
CC         COMP:10172, ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC         ChEBI:CHEBI:73995, ChEBI:CHEBI:82696; EC=2.1.1.98;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01084};
CC   -!- PATHWAY: Protein modification; peptidyl-diphthamide biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_01084}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01084}.
CC   -!- SIMILARITY: Belongs to the diphthine synthase family.
CC       {ECO:0000255|HAMAP-Rule:MF_01084}.
