Diphthine synthase

Diphthine synthase (DPS) is a S-adenosyl-L-methionine (SAM)-dependent methyltransferase. DPS catalyzes the trimethylation of a specific histidine residue in elongation factor 2 forming a diphthine and producing S-adenosyl-L-homocysteine (SAH). DPS participates in the diphthamide biosynthesis.
