An amalgamation of solid phase peptide synthesis and ribosomal peptide synthesis [PDF]
Peptide Science, 2008 AbstractExpressed protein ligation (EPL) is a protein semisynthesis technique that allows the site‐specific introduction of unnatural amino acids and biophysical probes into proteins. In the present study, we illustrate the utility of the approach through the generation of two semisynthetic proteins bearing spectroscopic probes. Dihydrofolate reductase

Solid-Phase Synthesis of Oxetane Modified Peptides [PDF]
Organic Letters, 2017 Solid-phase peptide synthesis (SPPS) is used to create peptidomimetics in which one of the backbone amide C═O bonds is replaced by a four-membered oxetane ring. The oxetane containing dipeptide building blocks are made in three steps in solution, then integrated into peptide chains by conventional Fmoc SPPS.

Epimerisation in Peptide Synthesis
Molecules, 2023 Epimerisation is basically a chemical conversion that includes the transformation of an epimer into another epimer or its chiral partner. Epimerisation of amino acid is a side reaction that sometimes happens during peptide synthesis.

Deprotection Strategies for Thioimidates During Fmoc Solid-Phase Peptide Synthesis: A Safe Route to Thioamides [PDF]
, 2019 Thioamides are important biophysical probes of peptide folding, but are prone to alpha-C epimerization during Fmoc solid-phase peptide synthesis. The stereochemical integrity of thioamide-containing peptides can be dramatically improved by protecting the
