2-(3-Carboxy-3-(methylammonio)propyl)-L-histidine

[3-[[4-(2-amino-2-Carboxy-ethyl)-1H-imidazol-2-yl]]-1-carboxy- propyl]-methyl-ammonium

C11H19N4O4 (271.1406)


2-(3-Carboxy-3-(methylammonio)propyl)-L-histidine is an unusual amino acid that results from the post-translational modification of histidine in certain proteins. In particular, it is a post-translational derivative of histidine that exists in protein synthesis elongation factor 2 (EF2) at the site of diphtheria toxin-catalyzed ADP-ribosylation of elongation factor 2. It is a precursor for diphthamide. This compound is a substrate for the enzyme diphthine synthase (EC 2.1.1.98). This enzyme catalyzes the chemical reaction: S-adenosyl-L-methionine + 2-(3-carboxy-3-aminopropyl)-L-histidine = S-adenosyl-L-homocysteine + 2-[3-carboxy-3-(methylammonio)propyl]-L-histidine [HMDB] 2-(3-Carboxy-3-(methylammonio)propyl)-L-histidine is an unusual amino acid that results from the post-translational modification of histidine in certain proteins.
