1. Equine glutathione transferase A3-3 : an efficient steroid isomerase
Abstract : Glutathione transferases (GSTs) comprise a superfamily of enzymes prominently involved in detoxication by making toxic electrophiles more polar and therefore more easily excretable. However some GSTs have developed alternative functions. READ MORE

2. Structure-Function Studies of Enzymes from Ribose Metabolism
Abstract : In the pentose phosphate pathway, carbohydrates such as glucose and ribose are degraded with production of reductive power and energy. Another important function is to produce essential pentoses, such as ribose 5-phosphate, which later can be used in biosynthesis of nucleic acids and cofactors. READ MORE

3. Computational Studies of Enzymatic Enolization Reactions and Inhibitor Binding to a Malarial Protease
Abstract : Enolate formation by proton abstraction from an sp3-hybridized carbon atom situated next to a carbonyl or carboxylate group is an abundant process in nature. Since the corresponding nonenzymatic process in water is slow and unfavorable due to high intrinsic free energy barriers and high substrate pKa s, enzymes catalyzing such reaction steps must overcome both kinetic and thermodynamic obstacles.

4. Evidence for adaptive variation at the genes coding for cytosolic phosphoglucose isomerase (PGIC) in Festuca ovina L
Abstract : The gene (Pgi) encoding the enzyme phosphoglucose isomerase (PGI) which plays a central role in the main pathways of carbon metabolism has been shown to be of adaptive significance in a wide range of different species. Earlier studies of enzyme electromorph variation in the grass Festuca ovina suggest that variation in cytosolic PGI (PGIC) may be involved in the adaptive response of F. READ MORE

5. Structural and Functional Studies of Ribose-5-phosphate isomerase B
Abstract : Ribose 5-phosphate isomerase (Rpi) is one of the major enzymes of the pentose phosphate pathway, where it catalyses the inter-conversion of ribose 5-phosphate (R5P) and ribulose 5-phosphate. Two forms of this isomerase with no significant amino acid sequence similarity exist, RpiA and RpiB. READ MORE
