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 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}.
