Cumulative Teaching Experience at Auburn:

BCHE 7220 Cellular and Molecular Enzymology (10´, 103 students, ~10 per offering)

BCHE 7200 Advanced Biochemistry I (6´, 145 students, ~24 per offering)

BCHE 5190/6190 General Biochemistry II (14´, 1,318 UG/68 G students, ~96/5 per offering)

BCHE 5180/6180 General Biochemistry I (5´, 639 UG/20 G students, ~128/4 per offering)

BCHE 6190 General Biochemistry II (prior to piggyback split) (6´, 488 students, ~81 per offering

CHEM 1030 Fundamentals of Chemistry I (1´, 211 students)

CHEM 1010 Survey of Chemistry II (1´, 119 students)

SCMH 1010 Concepts of Science (2´, 415 students, ~208 per offering)

CHEM 640 (16 students)/CHEM 646 (18 students) (qtrs, 1´ each – roughly equivalent to BCHE 7200)

The number of Biochemistry Division faculty combined with the number of section offerings for the large BCHE 5180/6180 and BCHE 5190/6190 courses has not enabled division faculty to teach outside of the department’s BCHE courses since 2009.

I was given release time from teaching in Fall 2017 to support progress on a new NSF grant, and to offset the increase in service commitment starting in Summer 2017 as the DBC Graduate Program Officer (GPO). Organizing and executing the New Graduate Student Seminar (Fall semesters) is part of GPO duties. The necessary tasks include soliciting participating faculty (multiple departments/units on campus), scheduling, generating material and presenting for two of the sessions, and monitoring student attendance. Since taking the position of Chair of the Department of Chemistry and Biochemistry, I have retained a diminished role in instruction.

4. B. RESEARCH

4.B.a Description of Research Program

Goodwin laboratory student success. An important measure of the success of this research program is the students who have contributed to its progress over years. Following the completion of their degrees (see 4.A.b.1 Dr. Goodwin as major professor), they have gone on to postdoctoral positions at some of the top institutions and labs in the country, including the National Institutes of Health, the Scripps Research Institute, Vanderbilt, Yale, Berkeley, Rice, University of Kentucky, Virginia Tech, Merck, and others. Several of my former students have since taken tenure-track faculty positions, and others have moved into positions in industry.

Broadly, the central interest of my research is in understanding the connections between enzyme structure and mechanism, including mechanisms of cofactor maturation, catalysis, inhibition, and irreversible inactivation. The enzymes under investigation in my laboratory are intimately connected to important physiological phenomena of substantial biomedical concern. These include host-pathogen interactions, virulence of bacterial and fungal pathogens, antibiotic resistance (particularly in tuberculosis), and the development of new antibiotic agents to fight organisms like Mycobacterium tuberculosis. Consequently, our progress in elucidating the enzyme structure-function connection carries important ramifications for understanding these broader concerns.

Catalase-peroxidase (KatG) Structure and Mechanism. A case-in-point is provided by KatG. The primary function of KatG is to degrade hydrogen peroxide (H₂O₂). Interestingly, in Mycobacterium tuberculosis (Mtb), KatG is also critical for the activation of the front line antitubercular agent isoniazid. Indeed, it has been estimated that over 70% of isoniazid resistant Mtb carry mutations that render KatG unable to catalyze isoniazid activation. Second, KatG is prominently distributed among some of the planet’s most notorious pathogenic organisms where its production is often connected with other virulence factors. This is true for both bacterial pathogens (e.g., the organisms that causes of tuberculosis and bubonic plague) and fungal pathogens (e.g., the organism that causes rice blast disease). This perhaps should not be too surprising given that a near universal response of higher eukaryotes (the intended hosts for these pathogens) is to produce large amounts of H₂O₂ to defend against infection.

The Goodwin laboratory has observed that peroxidatic electron donors (PxEDs) do not inhibit catalase activity as the entire field had anticipated, rather they stimulate catalase activity by at least an order of magnitude. PxED’s not only increase the efficiency of H₂O₂ degradation, but they also dramatically expand the pH range over which rapid H₂O₂ degradation can be expected. This new pH range matches precisely the conditions that infected hosts use to defend themselves against pathogens like those mentioned above. As we have investigated this phenomenon, we have uncovered that the PxED stimulatory effect and most aspects of KatG catalysis are connected to how the enzyme controls through-protein electron transfer. This has led to an NSF-funded project to evaluate intramolecular electron transfer as it relates to posttranslational formation of KatG’s novel MYW cofactor as well as how that cofactor is used for a completely novel mechanism of H₂O₂ degradation.

In addition, KatGs afford a novel opportunity for making advances in enzyme engineering, providing a platform for the development of new catalysts to address specific threats to human health. For enzyme engineering to be successful, it is essential that we understand the ways in which protein structures external to an active site can be used to modulate the function of that active site. KatGs are unique in that they use a single active site for two distinct catalytic activities: catalase and peroxidase. Amino acid sequence and protein structure comparisons reveal that KatGs and monofunctional peroxidases have highly similar active sites. However, the monofunctional peroxidases lack appreciable catalase activity. Sequence and structural analyses also reveal the presence of three large structures in KatGs that are absent from monofunctional peroxidases: two interhelical insertions and a C-terminal domain. All three of these features are peripheral to the active site. Thus, the KatGs represent an ideal opportunity to evaluate the mechanisms of active site modulation by peripheral protein structures. Consequently, our research holds great promise for making necessary advances to support efforts in enzyme engineering.

Identifying natural product inhibitors of M. tuberculosis shikimate kinase. As mentioned above, drug-resistant Mtb continues to pose a substantial threat to human health. Alarmingly, the FDA has only approved one new antitubercular agent since the 1960’s. Clearly, the need for new drugs to treat Mtb is pressing. Collaborating with Dr. Angela Calderón in the Drug Discovery and Development, we are investigating the shikimate pathway as a potential target for new antitubercular agents, and we are drawing on natural products as a source for new scaffolds for the development of such compounds. The shikimate pathway is particularly attractive for drug targets because it is essential for mycobacterial survival, but it is not present in humans. We are currently identifying natural product inhibitors for shikimate kinase. We are using mass spectrometry based rapid screening approaches to identify inhibitors, but it is not enough to simply identify such compounds. The compounds most likely to be successful as leads for new antitubercular agents must be mechanistically appropriate. That is, they must inhibit the aspects of the mechanism associated with shikimate (not present in human metabolism) but not those aspects of the mechanism associated with ATP (widely distributed in human metabolism). We are using site-directed mutagenesis to produce a panel of Mtb shikimate kinase variants for targeted intrinsic protein fluorescence studies. By selectively introducing tryptophan and by extension unique intrinsic fluorescent properties in each variant, we will have an approach to rapidly screen inhibitors for their binding properties including those aspects of the enzyme’s mechanism with which they interfere.
