Solid phase protein chemical synthesis.
The chemical synthesis of peptides or small proteins is often an important step in many research projects and has stimulated the development of numerous chemical methodologies. The aim of this review is to give a substantial overview of the solid phase methods developed for the production or purification of polypeptides. The solid phase peptide synthesis (SPPS) technique has facilitated conside...
متن کاملHis6 tag-assisted chemical protein synthesis.
To make more practical the total chemical synthesis of proteins by the ligation of unprotected peptide building blocks, we have developed a method to facilitate the isolation and handling of intermediate products. The synthetic technique makes use of a His6 tag at the C terminus of the target polypeptide chain, introduced during the synthesis of the C-terminal peptide segment building block. Th...
متن کاملAccessing human selenoproteins through chemical protein synthesis.
The human body contains 25 selenoproteins, which contain in their sequence the twenty-first encoded amino acid, selenocysteine. About a dozen of these proteins remain functionally uncharacterized or poorly studied. Challenges in accessing these selenoproteins using traditional recombinant expressions have prevented biological characterization thus far. Chemical protein synthesis has the potenti...
متن کاملChemical synthesis of a fully active transcriptional repressor protein.
Plasmid pLS1-encoded 45-amino acid transcriptional repressor CopG (formerly RepA) has been chemically synthesized. A one-step purification of the synthetic protein has been developed, which yields high levels of pure protein with low or no contamination of truncated products. We have compared some properties of the chemical CopG protein with those of the biologically purified CopG. The two prot...
متن کاملChemical synthesis and expression of the HIV-1 Rev protein.
The HIV-1 Rev protein is responsible for shuttling partially spliced and unspliced viral mRNA out of the nucleus. This is a crucial step in the HIV-1 lifecycle, thus making Rev an attractive target for the design of anti-HIV drugs. Despite its importance, there is a lack of structural, biophysical, and quantitative information about Rev. This is mainly because of its tendency to undergo self-as...
