How Protein folds? During translation, the linear chain of amino acids formed will be gradually released from the ribosome, and these amino acids should fold properly to make a functional protein, the ultimate nano machines in the cells. Protein folding is undoubtedly the most critical events that determine the ability of that given protein to work properly. <\/p>\n
How protein folds? Is it a random process? It shouldnt be, as folding determines the function. <\/p>\n
Definition: <\/p>\n
Protein folding refers to the set of ordered pathways by which protein folds into their native functional confirmation. <\/p>\n
Protein folding is primarily driven by hydrophobic forces.<\/p>\n
Anfinsen's Experiment <\/p>\n
First step.. <\/p>\n
The first insight to this question was provided by Christian Anfinsen at the NIH. He was working on the properties of ribonuclease A (a single chain protein of 124 amino acids with 4 di-sulphide bonds). He unfolded (denatured) ribonuclease A using urea and mercaptoethanol (denaturants). The protein lost its function. Then he allowed to renature ribonuclease A by removing denaturants, and found out that ribonuclease A folded spontaneously and become functional. He concluded that Ribonuclease A can self assemble into its 3D functional structure.<\/p>\n
Protein Folding inside the Cell <\/p>\n
Inside the cell, protein folding is assisted by different proteins collectively called as accessory proteins.<\/p>\n
