This entry represents the N-terminal domain of Diphthamide synthase. Diphthamide synthase catalyses the last amidation step of diphthamide biosynthesis using ammonium and ATP. Diphthamide synthase is evolutionarily conserved in eukaryotes. Diphthamide is a post-translationally modified histidine residue found on archaeal and eukaryotic translation elongation factor 2 (eEF-2) [1]. In some members of this family e.g. Swiss:Q12429, this domain is associated with Pfam:PF01042. The enzyme classification is EC:6.3.1.14.	Domain
