However, the corresponding Phe22 residue in OsDHAR is located too far away from the H-site bound GSH (distance between the NH of Phe22 and S of GSH was 6.5 ) for an interaction to occur, even after the conformational change 20
This condition is associated with a range of systemic complications, including cardiovascular, pulmonary, and psychological disorders ( Figure 2 ) ( Figure 2 RA is classified into two major subtypes based on the presence or absence of anti-citrullinated protein antibodies (ACPAs), detectable in around 67% of patients and serving as a key diagnostic marker ( Porphyromonas , Epstein-Barr virus, and gingivitis, along with noxious agents, dietary factors, and the gut microbiome, also contribute to ACPA generation ( Citrullination is catalyzed by the calcium-dependent enzyme protein arginine deaminases (PAD), converting neutral arginine into a polar citrulline residues in granulocytes and macrophages in RA patients ( The activation of major histocompatibility complex (MHC) Class II-dependent T-cells by citrullinated neoantigens promotes B-cells production of more ACPAs and the activation of inflammatory mediators like TNF-, IL-1, IL-6, and NF-B, leading to pannus formationa thickened synovial layer that invades and destroys cartilage and bone
Methods Construct design We initially tried expression of the full-length rat GluK3 subunit containing point mutants R591Q (Q/R site) but this construct had very low expression and poor profile on size exclusion chromatography (SEC) and hence was not suitable for structural analysis

Divalent iron is reoxidized to trivalent iron by membrane iron transporter auxiliary proteins, then binds to transferrin (TF) and is transported to various organs to perform physiological roles
