Description
Diphtheria toxin and some other bacterial toxins catalyse this reaction, which inactivates translation elongation factor 2 (EF2). The acceptor is diphthamide, a unique modification of a histidine residue in the elongation factor found in archaebacteria and all eukaryotes, but not in eubacteria. cf. EC 2.4.2.31 NAD(P)+-protein-arginine ADP-ribosyltransferase. The relevant histidine of EF2 is His715 in mammals, His699 in yeast and His600 in Pyrococcus horikoshii.
Form
Liquid or lyophilized powder
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC～-80 ºC.
Synonyms
ADP-ribosyltransferase; mono(ADPribosyl)transferase; NAD-diphthamide ADP-ribosyltransferase; NAD+:peptide-diphthamide N-(ADP-D-ribosyl)transferase
Reaction
NAD+ + diphthamide-[translation elongation factor 2] = nicotinamide + N-(ADP-D-ribosyl)diphthamide-[translation elongation factor 2]
