CC   -!- FUNCTION: Catalyzes the first step of diphthamide biosynthesis, i.e.
CC       the transfer of the 3-amino-3-carboxypropyl group from S-adenosyl-L-
CC       methionine (SAM) to the C2 position of the imidazole ring of the target
CC       histidine residue in translation elongation factor 2 (EF-2).
CC       {ECO:0000256|PIRNR:PIRNR004967}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-histidyl-[translation elongation factor 2] + S-adenosyl-L-
CC         methionine = 2-[(3S)-amino-3-carboxypropyl]-L-histidyl-[translation
CC         elongation factor 2] + H(+) + S-methyl-5'-thioadenosine;

CC         ECO:0000256|PIRNR:PIRNR004967};
CC   -!- PATHWAY: Protein modification; peptidyl-diphthamide biosynthesis.
CC       {ECO:0000256|ARBA:ARBA00005156, ECO:0000256|PIRNR:PIRNR004967}.
CC   -!- SIMILARITY: Belongs to the DPH1/DPH2 family.
CC       {ECO:0000256|PIRNR:PIRNR004967}.
CC   -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC       whole genome shotgun (WGS) entry which is preliminary data.
