An alloprotein is a novel synthetic protein containing one or more "non-natural" amino acids.Non-natural in the context means an amino acid either not occurring in nature (novel and synthesised amino acids), [1] or occurring in nature but not naturally occurring within proteins (natural but non-proteinogenic amino acids).
The established method for the production of synthetic peptides in the lab is known as solid phase peptide synthesis (SPPS). [2] Pioneered by Robert Bruce Merrifield , [ 4 ] [ 5 ] SPPS allows the rapid assembly of a peptide chain through successive reactions of amino acid derivatives on a macroscopically insoluble solvent-swollen beaded resin ...
Cell-free protein synthesis, also known as in vitro protein synthesis or CFPS, is the production of protein using biological machinery in a cell-free system, that is, without the use of living cells. The in vitro protein synthesis environment is not constrained by a cell wall or homeostasis conditions necessary to maintain cell viability. [ 1 ]
Protein synthesis is a very similar process for both prokaryotes and eukaryotes but there are some distinct differences. [1] Protein synthesis can be divided broadly into two phases: transcription and translation. During transcription, a section of DNA encoding a protein, known as a gene, is converted into a molecule called messenger RNA (mRNA).
Custom peptide synthesis provides synthetic peptides as valuable tools to biomedical laboratories. Synthetic oligopeptides are used extensively in research for structure-function analysis (for example to study protein-protein interfaces), for the development of binding assays, the study of receptor agonist/antagonists or as immunogens for the ...
Protein biosynthesis, the multi-step biochemical synthesis of proteins (long peptides) DNA synthesis, several biochemical processes for making DNA DNA replication, DNA biosynthesis in vivo; Synthesis (cell cycle) RNA synthesis, the synthesis of RNA from nucleic acids, using another nucleic acid chain as a template
The words protein, polypeptide, and peptide are a little ambiguous and can overlap in meaning. Protein is generally used to refer to the complete biological molecule in a stable conformation, whereas peptide is generally reserved for a short amino acid oligomers often lacking a stable 3D structure. But the boundary between the two is not well ...
In analogous experiments with other synthetic RNAs, they found that poly-C directed synthesis of polyproline. Nirenberg recounts that the labs of Severo Ochoa and James Watson had earlier done similar experiments with poly-A, but failed to detect protein synthesis because polylysine (unlike most proteins) is soluble in trichloroacetic acid.
