Identification
HMDB Protein ID HMDBP00407
Secondary Accession Numbers
  • 5644
Name Diphthine synthase
Synonyms
  1. Diphthamide biosynthesis methyltransferase
Gene Name DPH5
Protein Type Unknown
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).
Pathways
  • peptidyl-diphthamide biosynthesis
Reactions
S-Adenosylmethionine + 2-(3-Carboxy-3-aminopropyl)-L-histidine → S-Adenosylhomocysteine + 2-(3-carboxy-3-(trimethylammonio)propyl)-L-histidine details
