Protein

Diphthine methyl ester synthase

Gene

DPH5

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

S-adenosyl-L-methionine-dependent methyltransferase that catalyzes four methylations of the modified target histidine residue in translation elongation factor 2 (EF-2), to form an intermediate called diphthine methyl ester. The four successive methylation reactions represent the second step of diphthamide biosynthesis.2 Publications

Miscellaneous

2-[3-carboxy-3-(methylammonio)propyl]-L-histidine and the corresponding dimethyl compound can also act as acceptors.
Present with 13480 molecules/cell in log phase SD medium.1 Publication

Catalytic activityi

4 S-adenosyl-L-methionine + 2-((3S)-3-carboxy-3-aminopropyl)-L-histidine-[translation elongation factor 2] = 4 S-adenosyl-L-homocysteine + diphthine methyl ester-[translation elongation factor 2].1 Publication
