S-adenosyl-L-methionine + L-histidine-[translation elongation factor 2] = S-methyl-5'-thioadenosine + 2-[(3S)-3-amino-3-carboxypropyl]-L-histidine-[translation elongation factor 2] | unlike the enzymes in the radical S-adenosyl-L-methionine superfamily, Dph2 does not form the canonical 5'-deoxyadenosyl radical. Instead, it breaks the Cgamma,Met-S bond of S-adenosyl-L-methionine and generates a 3-amino-3-carboxylpropyl radical | Pyrococcus horikoshii |
