Research Overview
Microorganisms produce a large
variety of biologically active substances representing a vast
diversity of fascinating molecular architecture not available in any
other systems. Our research centers on the chemistry, biochemistry
and genetics of the biosynthesis of these secondary metabolites.
Blending organic chemistry, biochemistry, and molecular biology, we
take a multidisciplinary approach to study the secondary metabolism
by asking the following questions: what reactions are available in
nature, what are the enzymatic mechanisms of these reactions, how
are these reactions linked to produce complex structures, what are
the regulatory mechanisms of these pathways, and, ultimately, how
can we manipulate nature's biosynthetic machinery for the discovery
and development of new drugs. Members of our group gain broad
training spanning organic chemistry, biochemistry, microbiology and
molecular biology, a qualification that is becoming essential for
the modern bioorganic chemists who seek career opportunity in both
academia and pharmaceutical and biotechnology industry.
Current research projects
(i)
Cloning and characterization of
novel natural product biosynthetic gene clusters and machinery
(ii) Discovery and elucidation of novel enzymes, biochemistry, and
mechanism of catalysis
(iii) Engineering of natural product structure diversity by
combinatorial biosynthesis methods for drug discovery and
development
(iv) Expression of natural
product biosynthetic gene clusters in heterologous hosts for natural
product production and development of new strategies for
combinatorial biosynthesis
(v) Microbial natural product isolation and structural elucidation
for anticancer and antiinfective drug discovery
