Abstract:

In the search for selectivity, the aspartic proteases are known to be a very difficult case because the enzymes of this family are not only sequentially but structurally also very similar. To gain insight into the selectivity and specificity of the aspartic proteases family we characterized the binding sites of four malarial aspartic protease (plasmepsin I, plasmepsin II, plasmepsin IV, P. vivax plasmepsin) and two human aspartic proteases (cathepsin D and pepsin) with the intention of identifying the regions that could be potential sites for obtaining selectivity using molecular interaction field approach.

More about this publication?
  • Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
