PPT-Protein Folding and Processing

The classic principle of protein folding is that all the information required for a protein to adopt the correct threedimensional conformation is provided by its amino acid sequence Molecular chaperones. Ulrich Hartl and Manajit HayerHartl Ef57566cient folding of many newly synthesized proteins depends on assistance from molecular chaperones which serve to prevent protein misfolding and aggregation in the crowded environment of the cell Nascent chai Protein Folding and Molecular Chaperones Whereas many proteins can be refolded invitro under optimized conditions in good yields the situation in a living cellislessfavorableInparticularhighproteinconcentration an Muhammad Shoaib Amjad. 11-Arid-3758. PhD Botany. WHY PROTEIN FOLDING?. Most proteins must fold into defined three-dimensional structures to gain functional activity. . polypeptide chain -Immediate folding amplification Proteinsmediate virtually all cellular functions •Cellular structure •Transport across membranes –Import of nutrients –Export of Chris Garlock. Protein Folding - Why is it important. Proteins are biological nano-machines which play apart in all of our bodies functions. Protein folding is the process all proteins undergo to assemble into their native structure. Lecture 6. Structure of Proteins. Structural Groups. Protein Folding. Keratin. Collagen. Silk.

This has proved to be a very challenging problem. It has aptly been described as the second half of the genetic code, and as the three-dimensional code, as opposed to the one-dimensional code involved in nucleotide/amino acid sequence. .
