Research Description

My research program is concerned with the effects of extreme conditions on proteins and nucleic acids, and on the structural adaptations, organisms that live in these conditions have evolved to thrive in their environment. My lab will study these factors through a combination of experimental and computational biochemistry, structural biology, and ultimately, genetic experimentation with archaebacteria.

Proteins and nucleic acids are very sensitive to their chemical and physical surroundings. Like the organisms from which they are isolated, these molecules tend to function and remain stable over a relatively narrow range of environmental conditions such as temperature, pH, salinity, and pressure.

What those narrow conditions are, however, can vary widely. Most organisms grow best at about 37oC, under one atmosphere of pressure, with less than 0.2 M salt. But many archaebacteria do not; some grow in hot springs, for instance, or in hypersaline environments (such as the Great Salt Lake). These organisms must have evolved mechanisms to maintain the structural integrity of their proteins, nucleic acids, and membranes under these conditions, because human proteins, for instance, rapidly denature or lose activity when subjected to them.
