Peptides have a host of beneficial physiological effects and are often considered for therapeutic application to treat disease. However, poor bioavailabilities, problems with administration, sensitivity to environmental factors, and susceptibility to proteases limit them. The work presented in...

Paenibacillus polymyxa NRRL B-30509, Paenibacillus terrae NRRL B-30644 and P. polymyxa NRRL B-30507 were found to produce several bacteriocins and non-ribosomal peptides. All three strains produce tridecaptins, non-ribosomal lipopeptides antimicrobially active against food pathogen Campylobacter...

The lipopeptides, tridecaptin A1, tridecaptin B1 and cerexin A1 were isolated from Paenibacillus terrae NRRL B-30644, Paenibacillus polymyxa NRRL B-30507 and Bacillus mycoides ATCC 21929, respectively. A combination of chemical synthesis, peptide derivatization, high performance liquid...

Development and Application of Protected Amino Acids for the Installation of Stable Post-translational Modifications Using Solid-Phase Peptide Synthesis
DownloadFall 2022
This thesis describes the synthesis of non-canonical amino acid building blocks and their use in solid-phase peptide synthesis (SPPS) to explore peptidic drug analogues based on natural products. We replaced sensitive functionalities found in the structure of naturally produced peptides with...

Light Responsive Linchpins for Accelerated Discovery of Light-Responsive Mono- and Bicyclic Peptide Ligands
DownloadSpring 2016
In this thesis I describe the development and application of light-responsive (LR) linchpins for efficient discovery of LR-peptides from genetically encoded peptide librar-ies. LR-linchpins have been used for dynamic control of the structure of peptides and their biochemical properties such as...

Acidocin B (AcdB), a bacteriocin from Lactobacillus acidophilus M46 that was initially reported to be a linear peptide, was purified and shown to be circular based on MALDI-TOF MS and MS/MS sequencing. MS analysis further revealed that AcdB is comprised of 58 amino acid residues, instead of 59...
