Lymphoid enhancer-binding factor-1 (LEF-1), a member of the high-mobility group (HMG) family of proteins, functions as an architectural transcription factor. In complex with its cognate DNA, the LEF-1 domain is highly ordered, and its NMR spectra are characteristic of a folded globular protein. In contrast, the uncomplexed protein exhibits NMR evidence of(More)
Designing proteins with novel protein/protein binding properties can be achieved by combining the tools that have been developed independently for protein docking and protein design. We describe here the sequence-independent generation of protein dimer orientations by protein docking for use as scaffolds in protein sequence design algorithms. To dock(More)
The correlation between protein structure and function is well established, yet the role stability/flexibility plays in protein function is being explored. Here, we describe an in vivo screen in which the thermal stability of a test protein is correlated directly to the transcriptional regulation of a reporter gene. The screen readout is independent of the(More)
Protein fibril formation is implicated in many diseases, and therefore much effort has been focused toward the development of inhibitors of this process. In a previous project, a monomeric protein was computationally engineered to bind itself and form a heterodimer complex following interfacial redesign. One of the protein monomers, termed monomer-B, was(More)
We have devised and implemented a DNA fingerprinting module for an upper division undergraduate laboratory based on the amplification and analysis of three of the 13 short tandem repeat loci that are required by the Federal Bureau of Investigation Combined DNA Index System (FBI CODIS) data base. Students first collect human epithelial (cheek) cells using(More)
Engineered protein libraries, defined here as a collection of different mutant variants of a single specific protein, are intentionally designed to be rich in molecular diversity and can span ranges from as little as 400 different variants to greater than 10(12) members per library. The goal of engineering libraries is to generate new protein variants,(More)
Acknowledgements Many thanks to (in no particular order) Love for help, advice, and friendship during my time in the Mayo lab. You folks made the lab a great place to learn and do research. Thanks especially to Shannon Marshall for numerous interesting discussions, and to Chantal Morgan for teaching me how to take apart and reassemble nearly every(More)
Polyamides composed of N-methylpyrrole (Py), N-methylimidazole (Im) and N-methylhydroxypyrrole (Hp) amino acids linked by beta-alanine (beta) bind the minor groove of DNA in 1:1 and 2:1 ligand to DNA stoichiometries. Although the energetics and structure of the 2:1 complex has been explored extensively, there is remarkably less understood about 1:1(More)
