According to the working model, these cysteine residues may undergo chemical modification/remodeling including trisulfide bond formation and/or related reactions, resulting in a regional (minor, but effective) structural alteration that enhances c-met binding and the nitration resistance of Y198-HGF
The role of oxidative stress in the COVID-19 disease may involve recognition of the viral S-protein by angiotensin converting enzyme-2 (ACE2) receptor and pattern recognition receptors like toll-like receptors 2 and 4, and activation of transcription factors like nuclear factor kappa B, that subsequently activate nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (NOX) expression succeeded by ROS production (Kozlov et al., 2021)
