Protein-ligand interaction: a NMR study
Proteins perform numerous tasks within living organisms, some act as structural support for cells and tissues, others are transporters of non-soluble molecules in water and others, such as lysozyme, are involved in defensive mechanisms against bacterial attacks. The growing ease of obtaining proteins in substantial quantities and purity, by means of increasingly sophisticated bio-engineering techniques (1), may lead to their use in pharmaceutical formulations as drug delivery mechanisms or in food as preservatives (2).
