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
(Wiley, 2013-03)
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 ...
Unravelling the Photoprotection Capacity of Resveratrol on Histidine Oxidation
(Multidisciplinary Digital Publishing Institute, 2021-11)
Exposure to sun radiation causes great oxidative stress and activates a numerous of defense mechanisms in living systems, such as the synthesis of antioxidants. Resveratrol (RSV), a naturally occurring stilbene molecule, ...
Thermoanalytical study about histidine and cysteine-cadmium interactions
(Kluwer Academic PublDordrechtHolanda, 2003)
Conformational and Reaction Dynamic Coupling in Histidine Kinases: Insights from Hybrid QM/MM Simulations
(American Chemical Society, 2020-02)
Histidine kinases (HK) of bacterial two-component systems represent a hallmark of allosterism in proteins, being able to detect a signal through the sensor domain and transmit this information through the protein matrix ...
A comprehensive analysis of the computed tautomer fractions of the imidazole ring of histidines in Loligo vulgaris
(Adenine Press, 2017-09)
A recently introduced electrostatic-based method to determine the pKa values of ionizable residues and fractions of ionized and tautomeric forms of histidine (His) and acid residues in proteins, at a given fixed pH, is ...
Multiscale approach to the activation and phosphotransfer mechanism of CpxA histidine kinase reveals a tight coupling between conformational and chemical steps
(Academic Press Inc Elsevier Science, 2018-03)
Sensor histidine kinases (SHKs) are an integral component of the molecular machinery that permits bacteria to adapt to widely changing environmental conditions. CpxA, an extensively studied SHK, is a multidomain homodimeric ...
L-Histidine-europium(III) complex: A spectroscopical study
(1999-12-01)
Chemical characterization as well as spectroscopical study of the L-histidine-europium(III) complex were developed both experimental and theoretically. Molecular mechanics (MM) simulation was performed in order to have ...
