S-peptide is a crucial fragment derived from pancreatic ribonuclease A (RNase A), a well-studied enzymePeptide S is a novel potent inhibitor of voluntary and fast .... This 20-amino acid peptide, specifically the N-terminal portion of RNase A, plays a vital role in the enzyme's structure and function. When RNase A is cleaved between residues 20 and 21 by enzymes like subtilisin, it separates into two components: the larger S-protein and the s-peptide. These two fragments can reassociate to reform an enzymatically active ribonuclease S (RNase S), demonstrating a unique system for studying molecular recognition and protein-protein interactions.S Tag Peptide (25mg) Beyond its biochemical significance, s-peptide has gained prominence as a valuable tool in molecular biology, particularly as an epitope tag known as the S-tagRibonuclease S peptideand S protein offer a unique complementation system to understand the finer features of molecular recognition..

The Biochemical Significance of S-Peptide

The primary identity of s-peptide is its origin as a component of ribonuclease S.Merrifield s peptide resin 50-100mesh, loading 2.5-4.0 ... The re-binding of s-peptide to S-protein is a classic example of how specific sequences of amino acids can drive precise protein complex formation, leading to the restoration of biological activity.Purification of Synthetic Ribonuclease S-Peptide ... This interaction is characterized by high affinity, making the S-peptide/S-protein system a model for understanding how smaller peptide fragments can bind to larger protein structures. Researchers have extensively studied the mechanism of this dissociation and recombination, providing insights into protein folding and assembly.

S-Peptide as an Epitope Tag (S-tag)

In modern molecular biology, the s-peptide sequence has been adapted into a short, convenient epitope tag, commonly referred to as the S-tagA specific transition state for S-peptide combining with .... This 15-amino acid peptide sequence (often KETAAAKFERQHMDS) is fused to recombinant proteins of interest. The S-tag's small size minimizes interference with the target protein's function, while its unique sequence allows for specific detection and purification.S Tag Peptide is a 15 amino acid peptidederived from RNase A. For research use only. We do not sell to patients. Custom Peptide Synthesis. S ... This application is invaluable for protein purification and expression analysis, enabling researchers to easily identify and isolate proteins produced through genetic engineering. Antibodies specifically designed to recognize the S-tag are widely used in techniques like Western blotting, immunofluorescence, and affinity chromatography.Ribonuclease S-peptide. A model for molecular recognition.

Applications and Research Uses

The utility of s-peptide extends to various research applicationsS-tag Antibodies - Sino Biological. Its ability to act as a linker or a carrier in fusion proteins has been explored, leveraging its binding properties.作者：I Kato·1969·被引用次数：74—Ribonuclease S-protein andS-peptidewere separated by gel filtration on Sephadex G-75 (bead form, Phar- macia) in 50% acetic acid and lyophilized for storage. Furthermore, synthetic versions of s-peptide are available for research purposes, aiding in studies of protein interactions, enzyme kinetics, and the development of novel biochemical assays. The synthesis of peptides, including s-peptide, is a specialized field, with custom peptide synthesis services catering to specific research needs. While the primary context for s-peptide is biochemical and biotechnological, related concepts like Hemoglobin S, the protein involved in sickle cell disease, highlight the broader biological relevance of "S" designations in protein nomenclatureMechanism of dissociation of S-peptide from ribonuclease S. However, it's important to distinguish the ribonuclease s-peptide from other specific peptides that may bear similar naming conventions.
