Yu Q, Shi T, Xiong Z, Yuan L, Hong H, Gao R, Bao Y. Oxidation affects dye binding of myofibrillar proteins via alteration in net charges mediated by a reduction in isoelectric point. Food Res Int 2023; 163:112204. [PMID: 36596136 DOI: 10.1016/j.foodres.2022.112204] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 11/08/2022] [Accepted: 11/15/2022] [Indexed: 11/21/2022]
Abstract
In order to study the effect of oxidation on the dye-binding behavior of myofibrillar proteins, selected dyes with different charges (positively charged Sarfarin O (SO), neutral bromophenol blue (BPB), and negatively charged Orange G (OG)) were incubated with myofibrils oxidized by the Fenton system with H2O2 (10 mM). Upon oxidation, loss of free thiols, formation of carbonyls, particle size, and hydrophobicity of myofibrillar proteins (MPs) increased. The absolute value of Zeta-potential increased by 14.48 % after oxidation, the myofibrillar proteins shifted to a more acidic isoelectric point (pI) upon oxidation. Oxidation decreased net positive charges of myofibrillar protein and the binding ability of MPs towards OG in the environment with pH less than pI and the affinity of MPs towards SO in the environment with pH more than pI were thus increased. Here we propose a hypothesis that oxidation-induced change in net charges is the driving force affecting the amount of protein-bound dye. This paper aims to examine the effect of oxidation on the net charges of myofibrillar proteins and to provide insight into the mechanism of oxidation-induced changes in protein-bound dyes.

Abstract
The exposure of cells, tissues and extracellular matrix to harmful reactive species causes a cascade of reactions and induces activation of multiple internal defence mechanisms (enzymatic or non-enzymatic) that provide removal of reactive species and their derivatives. The non-enzymatic antioxidants are represented by molecules characterized by the ability to rapidly inactivate radicals and oxidants. This paper focuses on the major intrinsic non-enzymatic antioxidants, including metal binding proteins (MBPs), glutathione (GSH), uric acid (UA), melatonin (MEL), bilirubin (BIL) and polyamines (PAs).

Abstract
In this article, the interaction mechanism of Ga(3+)-hypocrellin A (Ga(3+)-HA) with myoglobin (Mb) is studied in detail through various spectroscopic technologies. UV-vis absorption and fluorescence spectra demonstrate the interaction process. The Stern-Volmer plot and the time-resolved fluorescence study suggest the fluorescence quenching mechanism of Mb by Ga(3+)-HA is a static quenching procedure, and the electronic transfer forces play a major role in binding Ga(3+)-HA to Mb. Furthermore, synchronous fluorescence studies and circular dichroism (CD) spectra reveal that the conformation of Mb is changed after its conjugation with Ga(3+)-HA.
