Diphthine synthase

Gene

dphB

Organism
Sulfolobus tokodaii (strain DSM 16993 / JCM 10545 / NBRC 100140 / 7)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

3 S-adenosyl-L-methionine + 2-((3S)-3-carboxy-3-aminopropyl)-L-histidine-[translation elongation factor 2] = 3 S-adenosyl-L-homocysteine + diphthine-[translation elongation factor 2].UniRule annotation

Pathwayi: peptidyl-diphthamide biosynthesis
