== Function == | |||
[https://www.uniprot.org/uniprot/DPHB_PYRHO DPHB_PYRHO] S-adenosyl-L-methionine-dependent methyltransferase that catalyzes the trimethylation of the amino group of the modified target histidine residue in translation elongation factor 2 (EF-2), to form an intermediate called diphthine. The three successive methylation reactions represent the second step of diphthamide biosynthesis.<ref>PMID:20873788</ref> | |||
