Research Interests of the group

  1. Enzyme behaviour, enzyme inhibition and enzymes with alternative functions.
  2. Systems biology.
  3. Enzymes and metabolic systems.

1. Enzyme Behaviour
(i) Mechanisms through which the copper-containing amine oxidase (semicarbazide-sensitive amine oxidase; EC also functions as a vascular-adhesion protein and modulates cellular glucose uptake.  
(ii) Mechanisms of the complex behaviour shown by the oxidase reaction catalysed by peroxidase (EC  
(iii) The multiple functions of ceruloplasmin (ferroxidase; EC  
(iv) The behaviour and applications of suicide inhibitors and suicide substrates.  

2. Systems Biology
Systems biology is the application of computational approaches to the understanding of the normal and dysfunctional behaviour of cellular systems.
Current projects include:
(i) Pathway tracing and metabolite connections.
(ii) Regulation of glucose transport in adipocytes and metabolism in normal and diabetic states.
(iii) Regulatory behaviour of branching processes.
(iv) Function and dysfunction of the aminergic nerve terminal.  
(v) Complex dynamics and their biological significance.
3. Enzyme Bioinformatics
We are responsible for curation of the International Union of Biochemistry and Molecular Biology's (IUBMB's) Enzyme List. This is a functional classification system in which novel enzymes are classified according to the reactions they catalyse, with each new enzyme being assigned an EC number. The work also involves updating entries for previously classified enzymes in the light of current knowledge. As the EC system is used extensively in many bioinformatics efforts, our group collaborates with many of the major world-wide bioinformatics centres, including the European Bioinformatics Institute, Cambridge (IntEnz), Kyoto University Bioinformatics Center (KEGG), University of Geneva (ExPASy and SWISS-PROT databases), University of Cologne (BRENDA database), University of Missouri at Columbia (KLOTHO database) as well as with IUBMB and IUPAC in this work.
