Identification
HMDB Protein ID CDBP00399
Secondary Accession Numbers Not Available
Name Diphthine synthase
Description Not Available
Synonyms
  1. Diphthamide biosynthesis methyltransferase
Gene Name DPH5
Protein Type Enzyme
Biological Properties
General Function Involved in methyltransferase activity
Specific Function 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 (By similarity).
