Research Summary

My research explores the diverse landscape of biological structure-function relationships, with the goal of improving our fundamental understanding of life processes. My current projects involve structure database development (EMDataBank, Protein Data Bank), with particular emphasis on improving representation of large biological assemblies.

Combining X-ray crystallography, electron microscopy and bioinformatics methods enables novel analyses. At promoters such as lac and gal, the E. coli catabolite activator protein (CAP) recruits RNA polymerase to promoter DNA.  Below at left is our original model of a class I CAP-dependent transcription activation complex (Lawson et al., 2004), created by combining several individual X-ray structures with additional biochemical information about protein-DNA contacts. An experimental 3D map volume of this complex using single particle averaging of 2D electron microscopy images (Hudson et al., 2009) is shown at right.  The EM reconstruction and an improved model based on the map are deposited in the EM Data Bank (EMD-5127) and PDB (id 3iyd) respectively.
