  • Current Research
  • Selected Publications

We are involved in the study of structural and mechanistic aspects of the biochemical function of various electron transfer and redox metalloenzymes using different physicochemical techniques.

Studies on wild type, and specifically designed mutant proteins are being carried out in the laboratory. The metalloenzymes currently being studied are:cytochrome c oxidase, cytochrome P450 and peroxidases. We are involved in the study of Enzyme kinetics, Protein stability and unfolding-refolding processes, protein engineering etc.

The following main techniques are used in these studies:
  • Circular Dichroism
  • Stopped-Flow
  • Micro-Calorimetry
  • Protein Mass Spectrometry (ESI-MS & MALDI-MS)
  • Protein Engineering Techniques
  • High-Eesolution NMR and Time-Resolved Fluorescence
