pH Dependence on Colorimetric Detection of Hg²⁺ by Histidine-Functionalized Gold Nanoparticles

Indonesian Journal of Chemistry, 2020
In this study, we successfully developed gold nanoparticles capped with histidine (His-AuNPs) for Hg2+ detection using trisodium citrate as the reducing agent. The optimum pH for the detection of Hg2+ by His-AuNPs was 12.

Effect of feeding histidine and β-alanine on carnosine concentration, growth performance, and meat quality of broiler chickens

Poultry Science, 2021
: The high growth rates of modern broiler breeds increased the risk for novel breast muscle myopathies as serious quality issue, relevant for the industry. In affected muscles, a depletion of the dipeptides carnosine and anserine was reported. Therefore,

Bioinspired Thiophosphorodichloridate Reagents for Chemoselective Histidine Bioconjugation [PDF]

, 2018
Site-selective bioconjugation to native protein residues is a powerful tool for protein functionalization, with cysteine and lysine side chains being the most common points for attachment owing to their high nucleophilicity.

[Roles of Histidine Kinases and Histidine Phosphatases in Cancer].

Zhongguo fei ai za zhi = Chinese journal of lung cancer, 2021
Phosphorylation is the most common and important post-translational modification of proteins, which plays an important role in the regulation of cell proliferation, differentiation, development and metabolism, and is closely related to the tumorigenesis and metastasis of cancer.

Significance of Histidine Hydrogen–Deuterium Exchange Mass Spectrometry in Protein Structural Biology [PDF]

Histidine residues play crucial roles in shaping the function and structure of proteins due to their unique ability to act as both acids and bases. In other words, they can serve as proton donors and acceptors at physiological pH.

Effect of supplementing rumen-protected methionine, lysine, and histidine to low-protein diets on the performance and nitrogen balance of dairy cows

Journal of Dairy Science, 2023
: Lowering the dietary protein content can reduce N excretions and NH3 emissions from manure and increase milk N efficiency of dairy cows. However, milk yield (MY) and composition can be compromised due to AA deficiency.
