Function of Conserved Residues of Human Glutathione Synthetase: Implications for the ATP-Grasp Enzymes
Article examining the mechanism of Glutathione synthetase, an enzyme that belongs to the glutathione synthetase ATP-binding domain-like superfamily. A variety of structural alignment methods were applied and four highly conserved residues of human glutathione synthetase (Glu-144, Asn-146, Lys-305, and Lys-364) were identified in the binding site. The function of these was studied by experimental and computational site-directed mutagenesis.

Analysis of the Fe 2p XPS for hematite 𝛂 Fe2O3: Consequences of covalent bonding and orbital splittings on multiplet splittings
Article analyzes the origins of the complex Fe 2p X-Ray Photoelectron Spectra (XPS) of hematite (α-Fe₂O₃) and is related to the character of the bonding in this compound. This analysis provides a new and novel view of the reasons for XPS binding energies (BEs) and BE shifts, which deepens the current understanding and interpretation of the physical and chemical significance of the XPS. This article is part of the JCP Special Topic on Oxide Chemistry and Catalysis.
