PPT-Protein Folding

The production of a mature protein is a multistep process in eukaryotic cells The final folded configuration or shape of a protein is determined by its amino acid sequence Most proteins require the assistance of molecular chaperones like Hsp70 amp Hsp60 to reach their final folded form.

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. .
