Macromolecular structure and function

We use x-ray crystallography to address how macromolecular structure determines function. We focus on several aspects: how do proteins interact with other macromolecules (RNA, DNA, proteins) or their substrates?  How do enzymes work, particularly those for which mechanistic insight is lacking? Protein structures also form the basis of protein engineering and for structure-based drug design. We are studying proteins of biotechnological interest (ie biofuel production) to provide for the much needed structural insight into these enzymes.
