Figure 1. The Bridwell-Rabb lab uses a combination of X-ray crystallography, enzymology, biophysical methods, and biochemical approaches to study how microbes engineer and modify light-dependent processes. Our goals are to investigate how the photosynthetic pigments chlorophyll and bacteriochlorophyll are modified to absorb a broader range of light (Project 1), how organisms build and tailor sunscreen pigments to provide protection from harmful UV-radiation (Project 2), and how light-dependent gene regulation is accomplished (Project 3).
