CC -!- FUNCTION: S-adenosyl-L-methionine-dependent methyltransferase that
CC catalyzes four methylations of the modified target histidine residue in
CC translation elongation factor 2 (EF-2), to form an intermediate called
CC diphthine methyl ester. The four successive methylation reactions
CC represent the second step of diphthamide biosynthesis.
CC {ECO:0000256|ARBA:ARBA00004006}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2-[(3S)-amino-3-carboxypropyl]-L-histidyl-[translation
CC elongation factor 2] + 4 S-adenosyl-L-methionine = diphthine methyl
CC ester-[translation elongation factor 2] + 3 H(+) + 4 S-adenosyl-L-
CC homocysteine; Xref=Rhea:RHEA:42652, Rhea:RHEA-COMP:9749, Rhea:RHEA-

CC Evidence={ECO:0000256|ARBA:ARBA00000054};
CC -!- PATHWAY: Protein modification; peptidyl-diphthamide biosynthesis.
CC {ECO:0000256|ARBA:ARBA00005156}.
CC -!- SIMILARITY: Belongs to the diphthine synthase family.
CC {ECO:0000256|ARBA:ARBA00006729}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the precorrin
CC methyltransferase family. {ECO:0000256|ARBA:ARBA00035662}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
