Our group is interested in understanding the structure-function relationship of radical-S-adenosylmethionine proteins that are used to modify small peptides found in ribosomally synthesized post-translationally modified peptide pathways. Once things get settled down, we'll provide you some more information. If you are really interested in knowing what we are working on behind our smoke screen, please feel free to contact the PI. We are always looking for collaborators and are always looking to help out fellow researchers.
