Introduction Methionine and cysteine are both sulphur containing amino acids. Most proteins will contain one‚ or both of them at some point in the polypeptide chain. As such‚ many amino acids contain sulphur in some form‚ which is required in small amounts in the mammalian diet. Methionine has a thioether side chain‚ and cysteine’s contains a thiol group. These side chains exist as free thiols inside the cell‚ and are oxidised causing them to pair up and form disulphide bonds in an extracellular

proteins are synthesized‚ Palade incubated slices of pancreatic tissue in radioactive amino acids for a short time period. By doing this‚ Palade & Jamieson found that the site of synthesis of secretory proteins is the endoplasmic reticulum. To follow the path of secretory proteins‚ the researchers furthered their experiment. They did this by washing the tissue and transferred it to a medium of unlabeled amino acids. This method is a “pulse-chase.” The pulse is the incubation period and the chase occurs

˚ N-1432 As‚ Norway Received 31 January 2001; received in revised form 10 May 2001; accepted 11 June 2001 Abstract Bacteriocins are antibacterial proteins produced by bacteria that kill or inhibit the growth of other bacteria. Many lactic acid bacteria ŽLAB. produce a high diversity of different bacteriocins. Though these bacteriocins are produced by LAB found in numerous fermented and non-fermented foods‚ nisin is currently the only bacteriocin widely used as a food preservative. Many

A protein structure consists of a specific sequence of amino acids called the primary structure‚ this particular sequence determines the secondary structure of the protein which can be α-helix or β-pleated sheet. This then further folds to form the tertiary structure . The primary structure determines the eventual

application is due by December 3. While I was in your class‚ I became fascinated with the fundamental processes of life that happen on a cellular level. I am very interested in working with Dr. Allen because I feel like his team’s research in amino acid therapies could make great advances in the field. I know that you have been a part of several successful related studies‚ and I would very much like to be part of a team that is working on something so important. In your class‚ I discovered my love
