Abstract:

Ribosomal incorporation of unnatural amino acids (AAs) into peptides or proteins has found broad applications in studying translation mechanism, discovering potential therapeutics, and probing protein structure and function. However, such applications are generally limited by the low incorporation efficiencies of the unnatural AAs. With in vitro kinetics studies using a purified E. coli translation system, we found that the natural N-alkyl AA carrier, tRNAPro, could hasten the incorporation of N-methyl AAs. Also, the incorporation rate increased remarkably with increasing pH in the range of 7

Abstract:

The "tag & modify" strategy for protein modification relies upon the genetic incorporation of an uncommon or unnatural amino acid into a protein backbone, followed by a chemo-selective modification to yield differentially modified proteins.

In Chapter 2, the unnatural amino acid, azidohomoalanine was genetically incorporated into a library of distance defined Np276 proteins via a selective pressure incorporation.

Abstract:

Proteins—polymers of amino acids—are a major class of biomolecules whose myriad functions facilitate many crucial biological processes. Accordingly, human control over these biological processes depends upon the ability to study, produce, and modify proteins. One innovative tool for accomplishing these aims is cell-free protein synthesis (CFPS). This technique, rather than using living cells to make protein, simply extracts the cells' natural protein-making machinery and then uses it to produce protein in vitro. Because living cells are no longer involved, scientists can freely adapt the prote

Homologous recombination (HR) is a means of repairing one specific type of damage, a double-strand break (DSB). This complex pathway includes the Rad51-DNA nucleoprotein filament as its primary machinery. Current methodology for studying HR proteins includes the use of fluorescently labeled DNA to probe for HR dynamics. This technique limits the number of proteins that can be involved in experimentation, and often only works as an end reporter. The work her

The allylic alcohols were then converted to protected allylic amines via Overman rearrangement chemistry. Oxidative alkene cleavage and hydrolysis of these intermediates generated a range of alpha-amino acid targets. Attempts were also made to apply the developed methodology to the s

Abstract:

The discovery of endogenous opioid peptides has greatly accelerated research in opioid chemistry and biology. Studies of the physiological and pharmalogical roles of these receptors require highly potent and receptor-selective ligands for μ, δ, and κ receptors. The major goal of this project is to design and synthesize highly potent and κ receptor-selective dynorphin A analogues with specific conformational and topographical features. Therefore, a series of linear and cyclic dynorphin A analogues with global and/or local conformational constraints have been designed, synthesized, and evaluated
