¨
Modeling
the catalytic chemistry in the enzyme peptide deformylase (PDF) and in non-heme
iron halogenases. The former is an
essential component in the life cycle of bacteria and an ideal new target for
antibacterial therapies; the latter catalyzes chemoselective halogenation of
natural products. For each enzyme, the
role of the metal ion and the effect of ligand modifications on the catalytic
reaction are being investigated. New
biomimetic model systems for the enzyme active sites are being designed to
better replicate the enzymatic catalysis.
¨
Determining
the reactivity of enediynes and related compounds with respect to their
tendency to cyclize upon thermal or photo-activation (project in collaboration
with Prof. John Spence, CSU, Sacramento Chemistry Dept.). The compounds can be used as pro-drugs for
DNA cleavage and have application in chemotherapy. Thermodynamics and kinetics of the
cyclization reactions along multiple pathways are calculated; at the same time,
UV/Vis spectra for the compounds are calculated and the associated electronic
excitations are characterized.
¨
Investigation
of the electrochemistry of metal-salen compounds and their potential for use in
the synthesis of pharmaceutically relevant organic compounds (project in
collaboration with Prof. James Miranda, CSU, Sacramento Chemistry Dept.). One aspect of research involves the
development of a computational chemistry method for the accurate determination
of reduction potentials for metal-salens.
A second research direction involves the study of the mechanism and
kinetics for electroreductive cyclization (ERC) reactions catalyzed by reduced
metal-salens.

September 2003 – July 2006. Professor
Christopher J. Cramer and Professor William B. Tolman,
advisors.
¨
Studied
the catalytic mechanisms of the dopamine ß-monooxygenase
(DßM) and peptidylglycine
α-hydroxylating monooxygenase
(PHM) enzymes by quantum chemical modeling of the active sites. The effects of different coordination
environments for the copper atoms on dioxygen
activation and substrate hydroxylation are determined. This work represents the first application of
theoretical methods to model specific reaction mechanisms in these enzymes and
will greatly increase understanding of the reaction chemistry of monocopper complexes in general.
¨
Modeled
dioxygen activation and substrate hydroxylation in
biomimetic monocopper complexes being developed in
the Tolman group.
This work was carried out in conjunction with parallel experimental
studies in the Tolman group.
¨
Mentored
and collaborated with an undergraduate student as a part of these two projects,
leading to publication (see #1 in publications).

· January 1999 – August 2003.
Professor Richard A. Friesner, advisor.
¨
Based upon ab initio quantum
chemical studies on a large-scale model, proposed for the first time complete
and realistic catalytic cycles for dioxygen
activation and methane hydroxylation by soluble methane monooxygenase,
a metalloenzyme that is found in methanotrophic
bacteria. Computational results were found to be fully consistent with and
provide explanation for experimental data.
Further work on this system succeeded in explaining the different rates
and kinetic isotopic effects seen in the reaction of methane monooxygenase with substituted methane substrates.
¨
Use of a novel mixed quantum mechanics/molecular
mechanics method (QM/MM) to determine the origin of the different rates for the
deacylation step in the hydrolysis of ß-lactam antibiotics performed by penicillin-binding proteins
and class-C ß-lactamases. This research played a role in understanding
the differences in reactivity of the two enzymes towards ß-lactam
antibiotics and contributed to an understanding of the mechanism of bacterial antibiotic
resistance.
