Assessing the fractions of tautomeric forms of the imidazole ring of histidine in proteins as a function of pH
(National Academy of Sciences, 2011-04-05)
A method is proposed to determine the fraction of the tautomeric forms of the imidazole ring of histidine in proteins as a function of pH, provided that the observed and chemical shifts and the protein structure, or the ...
Theoretical study of the adsorption of histidine amino acid on graphene
(IOP Publishing, 2016-05)
Previous studies have demonstrated how the interactions between biomolecules and graphene play a crucial role in the characterization and functionalization of biosensors. In this paper we present a theoretical study of the ...

Histidine oxidation photosensitized by pterin: PH dependent mechanism
(Elsevier Science Sa, 2015-12)
Aromatic pterins accumulate in the skin of patients suffering from vitiligo, a chronic depigmentation disorder, due to the oxidation of tetrahydrobiopterin, the biologically active form of pterins. In this work, we have ...
Determination of isoniazid in human urine using screen-printed carbon electrode modified with poly-L-histidine
(Elsevier B.V. Sa, 2010-02-01)
A sensitive voltammetric method for trace measurements of isoniazid (INZ) in synthetic human urine sample is described. The method is based on its electroreduction at -0.98 V vs. Ag/AgCl on screen-printed carbon electrode ...
The role of histidine in a copper-specific metallothionein
Metallothioneins achieve metal binding specificity by modulation of their amino acid sequences through evolution. Non-coordinating residues seem to play a key role in this function, and among them histidine may be of ...
