Research Overview

Our research is in the area of Molecular Enzymology - i.e. the characterization of structure, function and mechanism of enzymes with important biological and/or biotechnological roles. We have particular interest in the analysis of cofactor-binding proteins; particularly flavoproteins and flavoheme enzymes. Much of our research involves studies on mammalian proteins, including Nitric Oxide Synthases (NOSs), Methionine Synthase Reductase (MSR), and Cytochrome P450 reductases (CPR). Flavoproteins represent 1%–3% of all proteins present in prokaryotic and eukaryotic genomes and about half of the proteins involved in electron transfer. In addition, the scope of work extends to learning how other cellular proteins can control activity of   redox enzymes like NOSs and CPR, to cite a few. We are also interested in a membrane-associated enzyme NADPH oxidase (NOX) that catalyzes the production of superoxide.

Nitric Oxide (NO) is synthesized by NOS enzymes from L-arginine. They are calmodulin (CaM)-activated flavoheme enzymes contain connected NADPH-FAD (FNR), FMN, and NOSoxy domains that create a mini-electron transport chain to transfer NADPH-derived electrons to the heme and tetrahydrobiopterin (H4B) groups in the NOSoxy domain. These electron transfers enable O2 activation by the heme, an essential prerequisite for NO synthesis. The timing and rates of the electron transfers must be tightly regulated for NOS to generate and release NO while minimizing uncoupled NADPH oxidation and release of reactive oxygen species.

Area of research:

  • Understanding How Structure Controls Electron Transfer and Regulates Catalytic activity in Nitric Oxide Synthases (NOSs), Cytochrome P450 Reductase (CPR), Methionine Synthase Reductase (MSR) and related redox enzymes.
  • Domain-domain interaction studies in the NOS enzymes and regulation of Intramolecular electron transfer.
  • To develop novel strategies to tailor and correct NO production in cardiovascular and other diseases.
  • Understanding role of NO and NOSs in Asthma and Pulmonary Hypertension.
  • Investigating the mechanisms that control electron transfer between enzyme redox centers.
  • Investigating the mechanisms of electron transfer and Catalysis in Biomedically important flavoproteins and their role in human diseases.
  • Development and evaluation of lipid nanocarrier for Nitric Oxide Synthase delivery.
