WebbUsing multiscale simulation methods, we have characterized the interactions established by a peptidic substrate in the active site, and then we have explored the free energy … Proteolysis is the breakdown of proteins into smaller polypeptides or amino acids. Uncatalysed, the hydrolysis of peptide bonds is extremely slow, taking hundreds of years. Proteolysis is typically catalysed by cellular enzymes called proteases, but may also occur by intra-molecular digestion. Proteolysis in organisms … Visa mer Post-translational proteolytic processing Limited proteolysis of a polypeptide during or after translation in protein synthesis often occurs for many proteins. This may involve removal of the N-terminal methionine Visa mer Autoproteolysis takes place in some proteins, whereby the peptide bond is cleaved in a self-catalyzed intramolecular reaction. … Visa mer Protein backbones are very stable in water at neutral pH and room temperature, although the rate of hydrolysis of different peptide bonds can vary. The half life of a peptide bond under normal conditions can range from 7 years to 350 years, even higher for peptides … Visa mer Proteases may be classified according to the catalytic group involved in its active site. • Cysteine protease • Serine protease Visa mer Abnormal proteolytic activity is associated with many diseases. In pancreatitis, leakage of proteases and their premature activation in the pancreas results in the self-digestion of the pancreas. People with diabetes mellitus may have increased lysosomal activity … Visa mer Proteolysis is also used in research and diagnostic applications: • Cleavage of fusion protein so that the fusion partner and protein tag used in protein expression and purification may be removed. The proteases used have high degree of specificity, … Visa mer • Biology portal • The Proteolysis Map • PROTOMAP a proteomic technology for identifying proteolytic substrates • Proteasome • In-gel digestion Visa mer
