英文摘要
The basis of diseases and of their treatments resides in knowledge and
comprehension of the three-dimensional structures of proteins, nucleic
acids and other molecules. The availability of atomic-level structures,
advances made in understanding their mechanisms, and highly efficient
computational methodology that we have developed enables us to
investigate binding sites on molecular surfaces of receptors, and to
dock a ligand unto a receptor surface, which will be useful in the
design of potent inhibitors. We have recently developed and continue to
improve highly effective descriptions of molecular surfaces that are
successfully and efficiently utilized for docking molecules ranging in
size from small drugs to macromolecules. Using our sequence-order
independent, computer-vision based methods, interior and surface motifs
have been detected and catalogued. Using similar tools, a dataset of
protein-protein interfaces was made and utilized for studies of protein
associations and their comparison to protein folding. Comparisons of
this dataset to a dataset of protein monomers, generated earlier,
illustrates the similarities and differences between the types of
architectures at interfaces and in single-chain proteins. Theoretical
chemical methods are incorporated into the analyses and show that
hydrophilic effects are more important than hydrophobic forces in
interfaces. An efficient computational algorithm designed for cutting
proteins into highly hydrophobic, compact, subdomain modules is used to
produce a database of folding units that will provide deeper insights
into the architecture of proteins and how they are assembled.
RNA structure and function, no less important than that of proteins, is
studied using thermodynamics-based algorithms for secondary structure
and molecular mechanics and dynamics for three-dimensional predictive
modelling. Correlations drawn with experimental data from mutagenesis
and NMR show successful agreement in retroviral ribosomal frameshifting.
Internal ribosome entry in 5' untranslated regions (5' URT), a hallmark
of picornaviruses, correlates with conserved, predicted structural
elements. Similar elements are predicted in some 5'UTR's of cellular
mRNA's. Refinements in predictive methods are continually developed.
