Crystal structure of Glu140 to Asn mutant of Diphthine synthaseCrystal structure of Glu140 to Asn mutant of Diphthine synthase

Structural highlights

2egb is a 2 chain structure with sequence from Pyrococcus horikoshii. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:, , ,
Gene:dphB (Pyrococcus horikoshii)
Activity:Diphthine synthase, with EC number 2.1.1.98
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT, TOPSAN

Function

[DPHB_PYRHO] 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.[1]

Evolutionary Conservation
