Research Summary

My research since 2002 has been within a Computational Proteomics Project in collaboration with Prof. Maqsudul Alam of the University of Hawaii.   I have performed High level theoretical chemistry calculations on globular proteins (Ab Initio Molecular Dynamics characterizing ligand binding).   I have run extensive Molecular Dynamics simulations on globular proteins, helping to clarify their evolutionary development.   I have managed drug screening for dengue fever drugs in the envelope protein of flavivirus virion, both dimer and trimer.  I produced models of Gene Regulator proteins that are involved in a second messenger pathway.  This was achieved by a combination of homology modeling and threading—very complex structures were solved from sequence alone, advancing understanding of biofilm generation.

 

Drug Action Against Tumor
Drug Action Against Trimer
: The docked drug molecule prevents the trimer from forming by getting in the way of contacts that the
virus has to have occur for the trimer to “zipper”.  The cd loop regions  (“fusion loop”) on each trimer section come together
for insertion  into the cell membrane, making the virus effective.
