Enzyme Information
| 2.1.1.98 |
Diphthine synthase.
based on mapping to UniProt O29866
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].
-!- This archaeal enzyme produces the trimethylated product diphthine, which is converted into diphthamide by EC 6.3.1.14. -!- Different from the eukaryotic enzyme, which produces diphthine methyl ester (cf. EC 2.1.1.314). -!- In the archaeon Pyrococcus horikoshii the enzyme acts on His(600) of elongation factor 2.
