Contributions in structural biology

Sujata Sharma was the first structural biologist to successfully demonstrate the proteolytic production of N- and C-terminal molecular halves of Lactoferrin, crystallize the C-lobe and determine the three-dimensional structure [10] [11] Her studies have established the fact that lactoferrin has a direct role in chelating the unbound non-steroidal anti-inflammatory drugs (NSAIDs) which in turn leads to the reduction in the NSAID-induced gastropathy. [12]

The studies on the structure determination of Peptidoglycan Recognition Protein which is a component of the innate immune system and are conserved from insects to mammals, have given a new direction for the development of this protein as a natural protein antibiotic. [13] [14] The structural studies on the lactoperoxidase system, that is, lactoperoxidase along with its inorganic ion substrates, hydrogen peroxide, and oxidized products have given new insights into the structure-function interrelationships of this antimicrobial protein. [15] [16] Her structural studies on SPX-40 have demonstrated that the molecule acts as a protective signalling factor for breast cancer cells and have validated this protein as a drug target for breast cancer. [17] She has also been involved in the designing of inhibitors, both small organic and inorganic compounds and peptides, against these protein targets. She has successfully demonstrated the potency of these ligands in several animal models.

Lactoperoxidase is a peroxidase enzyme secreted from mammary, salivary and other mucosal glands including the lungs, bronchii and nose that functions as a natural and the first line of defense against bacteria and viruses. Lactoperoxidase is a member of the heme peroxidase family of enzymes. In humans, lactoperoxidase is encoded by the LPO gene.

Pathogenesis-related (PR) proteins are proteins produced in plants in the event of a pathogen attack. They are induced as part of systemic acquired resistance. Infections activate genes that produce PR proteins. Some of these proteins are antimicrobial, attacking molecules in the cell wall of a bacterium or fungus. Others may function as signals that spread “news” of the infection to nearby cells. Infections also stimulate the cross-linking of molecules in the cell wall and the deposition of lignin, responses that set up a local barricade that slows spread of the pathogen to other parts of the plant.
