Function of Conserved Residues of Human Glutathione Synthetase: Implications for the ATP-Grasp Enzymes (open access)

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.

Cluster embedding of ionic systems: Point charges and extended ions (open access)

Cluster embedding of ionic systems: Point charges and extended ions

This article presents a detailed analysis of the orbital energies of a representative cluster model of a high spin metal oxide, FeO, that has been made to determine the importance of different embedding schemes to represent the extended oxide crystal. The embedding of cluster models of oxides with point charges and with extensions of the embedding which take into account the spatial extent of the cations is examined with an emphasis on the consequences of this embedding for the relative ionization and excitation energies that are measured in core-level spectroscopies.
