University of Texas Health Science Center at Houston Medical School Biochemistry and Molecular Biology Assistant ProfessorAppointed: 2000 University of Texas Health Science Center at Houston Medical School Structural Biology Research Center DirectorAppointed: 2002 |  |
QualificationsPh.D., University of Texas Health Science Center at San Antonio, Biochemistry and Biophysics, 1996. Expertise and Research InterestsCutting edge structural and biological research performed under one roof. We not only solve macromolecular structures using X-ray crystallography, but also utilize prokaryotic, unicellular eukaryote (Chlamydomonas and Saccharomyces), invertebrate (C. elegans), and vertebrate (zebrafish) model sytems to investigate functional correlations.
Ongoing Research Projects:
1. Structural Biology of Nitric Oxide Synthase-like Proteins from Human Pathogens
Funding: NIH, Pew
We are investigating structure-function relationships in the newly discovered nitric oxide synthase-like proteins from Anthrax bacterium and Staphylococcus aureus.
Pierre Nioche (Research Assistant Professor) is the primary contributor to this project.
Collaborators: Jean-Luc Boucher (Paris), Brian Hoffman (Evanston), Theresa Koehler (Houston), Daniel Mansuy (Paris), Pavel Martasek (Prague), Martin Newcomb (Chicago).
2. Substrate and Inhibitor Recognition by Mammalian Nitric Oxide Synthases
Funding: The Robert A. Welch Foundation, NIH/NINDS
This project focuses on crystallographic studies aimed at understading how substrate and inhibitors are selectively recognized by the mammalian nitric oxide synthase machine. In addition we are also investigating the structural networks responsible for electron transfer processes.
Pierre Nioche, Dong-Sun Lee (Research Assistant Professor), and Raegan Hunt (M.D./Ph.D. student) contribute to this project.
Collaborators: Rosa Claramunt (Spain), Jose Elguerro (Spain), Dominique Vichard (Versailles), Francois Terrier (Versailles), Vladimir Kral (Prague), Pavel Martasek (San Antonio), Bettie Sue Siler Masters (San Antonio).
3. Structural Bases of Gaseous Messenger Signal Transduction
Funding: Pew, The Robert A. Welch Foundation
Three decades of research has failed to identify the molecular bases of how gaseous messengers transduce signals to mediate a variety of cellular responses. We have put in place strategies that will both overcome the hurdles experienced by other researchers and provide atomic insights into the mechanisms of signalling by nitric oxide and carbon monoxide.
Pierre Nioche is the primary contributor to this project.
Collaborators: Andrew Camilli (Boston), Peter Ford (Santa Barbara), James Kaper (Baltimore), Nigel Minton (Nottingham) , Michel Negrerie (Paris), John Olson (Houston), Masao-Ikeda Saito (Japan), Takeshi Tomita (Japan), Sudha Veeraraghavan (Houston).
4. Structure-Function Relationships in Heme Biosynthesis
Funding: Pew, The Robert A. Welch Foundation
We study how heme is biosynthesized, transported and degraded in eukaryotes.
Nathan Campbell (Senior Research Assistant) is the primary contributor to this project.
5. Structural Biology of Lipid Mediator Signaling
Funding: Pew, The Robert A. Welch Foundation
We are exploring the enzymes that biosynthesize thromboxane A2 and prostacyclin (PGI2) in humans.
Dong-Sun Lee, Raegan Hunt, & Pierre Nioche contribute to this project.
Collaborators: Volker Ullrich (Konstanz), Didier Stainier (San Francisco), JD (Belgique), and JMD (Belgique).
6. Novel Regulators of Mitochondrial Homeostasis
Funding: Pew, NIH/NINDS
We have discovered novel proteins that modulate mitochondrial function. Structure-function studies are in progess to elucidate the mechanisms by which this key process is regulated.
This is the dissertation project of Raegan Hunt.
Collaborators: Yurii Chinenov (New York), Pavel Martasek (Prague), Didier Stainier (San Francisco).
7. Structural Bases of Immunodeficiency
Funding: Pew
We are engaged in X-ray crystallographic studies of Activation-Induced Deaminase (AID).
