Step 1: When substrate (polypeptide) binds, the side of chain of the residue next to the peptide bond to be cleaved nestles in a hydrophobic pocket on the enzyme, positioning the peptide bond for attack. Histidine extracts one proton from serine to form an alkoxide ion. This serine ion reacts with the substrate. Step 2: In chymotrypsin, the carboxylate R-group of Asp102 forms a hydrogen bond with R group of His 57. When this happens, it compresses this hydrogen bond and shifts electron…

Why is it so Important for Our Health? Glutathione also known as GSH, is a small tripeptide molecule composed of three amino acids – Glutamic Acid, Glycine, and Cysteine. All three amino acids must be present for the cell to produce GSH. The largest concentration of glutathione is in the liver. Glutathione, or GSH, is found in every cell in the body and is also available as a supplement. There are many... FULL ARTICLE @ http://www.engineeredlifestyles.com/glutathione/glutathione.html

Proteasome: protein complex inside all eukaryotes and archaea and in some bacteria; in eukaryotes, they are located in the nucleus and cytoplasm; main function: to degrade unneeded or damaged proteins by proteolysis (chemical reaction that breaks peptide bonds); proteases: enzymes that carry out these reactions; part of a major mechanism by which cells regulate concentration of particular proteins and degrade misfolded proteins
