Research ArticleOpen accessIn the keywordsGenomic Distance between Thymidylate Synthase and Dihydrofolate Reductase Genes Does Not Correlate With Phylogenetic Evolution in BacteriaVitor Hugo MoreauProblem statement: Dihydrofolate Reductase (DHFR) and Thymidylate Synthase (TS) exist as bifunctional enzymes coded into unique polypeptide chain in protozoans. Bifunctional DHFR-TS is associated with an increase in the enzymatic activity by channeling the substrate between the active sites. In some bacteria, DHFR and TS genes are neighbors in the genome, whereas in others, they are located millions of base … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 1 · 31 Mar 2010 · 8,188 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparative Physiological and Molecular Study of Some Sheep Breeds in Saudi ArabiaMohammad S. AL-Harbi, Hamed S. Alwagdany, Sayed A.M. AmerNaemi, Heri, Najdi and Sawakni sheep breeds inhabiting Kingdom of Saudi Arabia were studied on both physiological and molecular bases. Native polyacrylamide gel-electrophoreses for two enzymes Malate Dehydrogenase (Mdh) and Malic Enzyme (Me) recorded 5 isoenzyme loci from which 4 were polymorphic and 1 was monomorphic. Mdh showed three fractions, the first was recorded in Sawakni and Najdi breeds, the … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 20 Jun 2013 · 8,388 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMolecular Analysis of Coagulase Gene Polymorphism in Clinical Isolates of Methicilin Resistant Staphylococcus aureus by Restriction Fragment Length Polymorphism Based GenotypingM. Himabindu, D. Sugapriya Muthamilselvan, Dillip Kumar Bishi, Rama S. VermaProblem statement: To investigate coagulase gene variants through Restriction Fragment Length Polymorphism (RFLP) amongst clinical isolates of Methicillin-Resistant Staphylococcus Aureus (MRSA) collected from Chennai based hospitals. Approach: A total of 85 MRSA clinical isolates collected from various clinical sources were studied for the molecular typing purpose. To perform coagulase gene typing, the repeated units encoding hypervariable regions of the Staphylococcus … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 8,766 accessesView PDF Cite
