  • Monoclonal antibodies neutralizing snake venom long & short chain three finger neurotoxins

    Snakebite envenomation is a neglected tropical disease killing >135,000 people annually, predominantly in developing countries. Polyvalent antivenom is the only treatment, but it’s made through outdated technology. Monoclonal antibodies (mAbs) are the logical alternative for developing next-generation antivenom medicines. Here, we isolated a pair of antivenom mAbs that broadly cross-neutralized long and short chain three…

  • Modelling the covalent intermediates of the nitrilase superfamily

    The nitrilase superfamily, which includes amidases, are thiol enzymes that catalyze the hydrolysis and condensation of non-peptide, carbon-nitrogen linkages. The mechanism of action of these enzymes remains unknown – but substantial insight has been gained from our studies of the closely related amidases. All the enzymes have a structurally conserved active site grouping comprising two…

  • Structural insights into the lysine-specific uptake mechanism for extremely low pH regulation by bacteria

    Under conditions of extremely low pH, in addition to transporting lysine, the lysine-specific permease (LysP) interacts with the transcriptional regulator CadC to upregulate cadBA operon expression. cadBA encodes CadA, which decarboxylates lysine to cadaverine, and CadB, which exports the alkaline product (cadaverine) to the environment to reduce acidity. This process is crucial for bacterial survival…

  • Structural insights in DNA replication and repair

    Structural biology has been the most successful applications of physics to biology, providing atomic information on several thousands of macromolecules and complex macromolecular machines. Among these machines, I have always been fascinated by helicases, a family of proteins that act as molecular motors, using the energy from ATP hydrolysis to move along the DNA and…
