Crystallization and preliminary diffraction studies of TraF, a component of the Escherichia coli type IV secretory systemDownload
TraF, a component of the Escherichia coli type IV secretory system, has been crystallized and preliminary X-ray diffraction data have been collected. TraF is a 26 kDa protein encoded by the E. coli F plasmid and is required for conjugative plasmid transfer and the formation of sex pili. The...
Although sumoylation regulates a diverse and growing number of recognized biological processes, the molecular mechanisms by which the covalent attachment of the ubiquitin-like protein SUMO can alter the properties of a target protein remain to be established. To address this question, we have...
Bacterial conjugation is the process of plasmid DNA transfer from a donor cell to a recipient cell. This process is mediated in F-like plasmids by proteins expressed by the tra operon. The relaxosome forms at oriT (origin of transfer), where the nicking and unwinding of a single-stranded copy of...
Synthesis, Structure and Properties of a Novel “Frustrated” Benzoxaborole and the Role of Boron in BioconjugationDownload
Chapter 2 describes an optimized 7-step successful synthesis of a first of its kind permanently open-form ortho-hydroxyalkyl arylboronic acid, otherwise known as a “frustrated benzoxaborole”, with a columnless purification and complete structure elucidation. This novel compound is completely...
