laboratory is involved in several projects. 1. Pathogenesis of dormancy
in Mycobacterium tuberculosis: It is widely and believed that oxygen
limitation, amino acid starvation and carbon source restriction are
involved in establishing and maintaining Mycobacterium tuberculosis
in a dormant state. Correspondingly, emergence from dormancy is related
to a partial or complete amelioration of these conditions. The lab identified
three genetic and enzyme systems that comprise regulatory networks in
M.TB that may be involved in pathogenesis. 2. Enzymology and cell biology
of serine proteases and serine protease inhibitors: Serine proteases
and serine protease inhibitors (serpins) play critical roles in inflammation,
coagulation, growth and development. The lab has proposed a general
model for the mechanism of inhibition of serine proteases by serine
protease inhibitors based on site directed mutagenesis, atomic resolution
crystal structures and NMR spectroscopic analyses, and is exploring
the consequences and extensions of this model. 3. Biomolecular Computation:
A new area of investigation is known as biomolecular computation where
complex computational operations are carried out using biomolecules,
in particular using DNA. The lab showed how macromolecules can be manipulated
to carry out fundamental logical operations and can be wired together
as reversible logic gates. The lab is collaborating with members of
the School of Engineering on modeling complex biological behavior using
a hybrid systems approach that combines continuous and stochastic modalities.
