2-(3-amino-3-carboxypropyl)histidine synthase.
based on mapping to UniProt O58832
L-histidine-[translation elongation factor 2] + S-adenosyl-L-methionine = 2-((3S)-3-amino-3-carboxypropyl)-L-histidine-[translation elongation factor 2] + S-methyl-5'-thioadenosine.
-!- Modifies a histidine residue of the translation elongation factor 2 (EF2) via a 3-amino-3-carboxypropyl radical. -!- The enzyme is present in archae and eukaryotes but not in eubacteria. -!- Part of diphthamide biosynthesis. -!- Formerly EC 2.5.1.n7.
