WebbHistidine (symbol His or H) [2] is an essential amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated –NH 3+ form under biological conditions ), a carboxylic acid group (which is in the deprotonated –COO − form under biological conditions), and an imidazole side chain (which is ... Webb15 jan. 2000 · Histidylated oligolysines are supposed to favor the delivery of ODN into the cytosol by permeabilizing the endocytotic vesicles which contain both ODN and oligomers. This destabilization probably involves the protonation of imidazole groups in the acidic lumen of endosomes.
