Download or read book Hybrid phase Native Chemical Ligation Approaches to Overcome the Limitations of Protein Total Synthesis written by Ruixuan Ryan Yu and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Total protein synthesis allows the preparation of proteins with chemically diverse modifications. The numerous advantages of total synthesis are sometimes offset by some major limitations. Protein synthesis is a non-trivial task involving many chemical steps, and these steps increase with the size of the protein. Therefore, larger proteins are difficult to synthesize with high yield. We have developed a strategy which we term hybrid-phase native chemical ligation (NCL) to overcome some of the limitations of size and yield. Hybrid-phase NCL combines ligating peptides on a solid support (solid-phase NCL) and in solution (solution-phase NCL) to maximize synthetic yield. We have successfully used this method to synthesize triple-acetylated histone H4-K5ac,K12ac,K91ac and, for the first time, acetylated centromeric histone CENP-A-K124ac (CpA-K124ac). In order to improve the yield of CENP-A total synthesis, we have incorporated a convergent ligation element in our hybrid-phase strategy. This new approach reduced the number of purification steps, leading to a synthetic yield that was almost triple that of the original approach. Finally, we introduce the convergent solid-phase hybrid NCL approach that allows the preparation of a long peptide segment bearing a masked thioester on a solid support. Through a newly developed resin-anchoring strategy, cleavage of the product from solid-phase generated a ligation-compatible segment that could be used directly with no purification. This method has the potential to synthesize large proteins in good yield, effectively overcoming the size and yield limits of protein total synthesis.

Abstract: Abstract of thesis entitled TOTAL SYNTHESIS OF GLYCOSYLATED INTERLEUKIN-25 VIA INTEGRATED CHEMICAL LIGATIONS Submitted by Chi Lung LEE for the degree of Doctor of Philosophy at The University of Hong Kong in April 2016 Chemical protein synthesis is a powerful tool as it can exert atomically precise control on the composition of protein and, thus, can overcome the potential limitations of protein expression. It enables the assembly of complex and homogeneous proteins bearing site-specific post-translational modifications, such as glycosylation, for the study of structure-activity-relationship (SAR) of proteins. To maximize the efficiency of protein synthesis, a convergent synthetic approach is adopted as this involves ligations in both the N-to-C and C-to-N direction which are inherently parallel and complementary. To this end, kinetically controlled ligation (KCL) was developed. However, for the synthesis involving multi-fragments ligation using serine/threonine ligation (STL), current strategies are suitable only for the sequential ligations in the C-to-N direction. In this thesis, a novel N-to-C assembly strategy has been developed for STL-based convergent ii synthesis of protein/glycoprotein. The key to the success in STL in the N-to-C direction was the use of semicarbazone as a protecting group to selectively switch on/off on and off the activity of the peptide salicylaldehyde (SAL ) ester, permitting the control of the dual activity of peptide containing N-terminal Ser/Thr and C- terminal SAL ester. By combining this strategy with traditional C-to-N STL, convergent synthesis by STL is now realized. In addition to STL, a combined ligation strategy involving sequential STL and NCL was also revealed in the N- to-C direction. This new strategy could significantly increase the choices for ligation sites and thus allow the assembly of protein targets bearing insufficient cysteines or cysteines next to proline or valine. The feasibility of the N-to-C assembly using an integrated ligation strategy to produce peptide fragments for convergent synthesis was demonstrated by the synthesis of an N-glycosylated protein Interleukin (IL)-25 (also known as IL-17E), where its aggregation-prone nature at its C-terminal end renders its synthesis difficult via traditional C-to-N STL. With this successful illustration, it is anticipated that the compatibility of STL and NCL will provide a versatile approach for the future convergent synthesis of proteins of many kinds. iii Subjects: Interleukins

Download or read book Convergent Hybrid phase Ligation Synthetic Strategy Combined with Direct Refolding Method to Improve Synthetic Yield of Centromeric Protein A written by Xiaoyu Zhang and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Histone proteins are a series of post-translational modification (PTM) heavy proteins. Total protein chemical synthesis possesses advantages in preparation of these protein samples containing specific PTM(s). However, the synthetic yield is always one of the biggest limitation of total protein chemical synthesis, especially when preparing large protein sample. Our lab had developed a synthetic strategy to total synthesize the H3 variant, Centromeric protein A (Cenp- A). Even though the synthesis was successful, the overall synthetic yield still did not fulfil our expectation. Here, we have developed a new convergent hybrid-phase synthetic strategy combined with direct histone octamer refolding and applied on the total synthesis of Cenp-A. This new strategy could maximally utilize the advantage of solid-phase native chemical ligation and avoid the any solution-phase purification steps which turned out to be the main reason of causing yield loss during the synthesis. This new synthetic strategy holds potential of greatly improving the synthetic yield of Cenp-A and being applied on the total synthesis of other large proteins.
Download or read book Amino Acids Peptides and Proteins in Organic Chemistry Building Blocks Catalysis and Coupling Chemistry written by Andrew B. Hughes and published by John Wiley & Sons. This book was released on 2011-08-08 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the third of five books in the Amino Acids, Peptides and Proteins in Organic Synthesis series. Closing a gap in the literature, this is the only series to cover this important topic in organic and biochemistry. Drawing upon the combined expertise of the international "who's who" in amino acid research, these volumes represent a real benchmark for amino acid chemistry, providing a comprehensive discussion of the occurrence, uses and applications of amino acids and, by extension, their polymeric forms, peptides and proteins. The practical value of each volume is heightened by the inclusion of experimental procedures. The 5 volumes cover the following topics: Volume 1: Origins and Synthesis of Amino Acids Volume 2: Modified Amino Acids, Organocatalysis and Enzymes Volume 3: Building Blocks, Catalysis and Coupling Chemistry Volume 4: Protection Reactions, Medicinal Chemistry, Combinatorial Synthesis Volume 5: Analysis and Function of Amino Acids and Peptides This third volume in the series presents an in depth account of recent developments in the (bio-)synthesis of amino acids and peptides. Divided into two parts, the first section deals with amino acids as building blocks, including the generation of alpha-amino acids, beta-lactams, and heterocycles. The second section is devoted to the synthesis of peptides, with the focus on solid phase synthesis. However, solution phase peptide synthesis is covered as well, as are topics such as coupling reagents, chemical ligation, peptide purification and automation. Originally planned as a six volume series, Amino Acids, Peptides and Proteins in Organic Chemistry now completes with five volumes but remains comprehensive in both scope and coverage. Further information about the 5 Volume Set and purchasing details can be viewed here.
