It states that, at least for a small globular protein in its standard physiological environment, the native structure is determined only by the protein's amino acid sequence. The dogma was championed by the Nobel … See more Protein folding in a cell is a highly complex process that involves transport of the newly synthesized proteins to appropriate cellular compartments through targeting, permanent misfolding, temporarily unfolded states See more • Sela M, White FH Jr, Anfinsen CB (1957).

WebMore intriguingly, in 1957 Anfinsen reported that denatured enzyme with completely reduced sulfydryl residues could recover activity spontaneously, after removal of the denaturant and re-oxidation of some of the disulfide bonds through exposure to air. This provided the core observation underlying Anfinsen’s subsequent experiments. The Nobel ... Web5.
