Chaperones are:

CHAPERONES-FOLDING /SHAPE /ASSEMBLY OF PROTEIN POST-TRANSITIONAL CHANGE They facilitate and our the interactions on the polypeptide surfaces to finally give the specific conformation of a protein. Type 1. Hsp70 system- This mainly consists of Hsp70 (70-kDa heat shock protein) and Hsp40 (40-kDa Hsp). These proteins can bind individually to the substrate (protein) and help in the correct formation of protein folding 2. Chaperonin system: This is a large oligomeric assembly which forms a structure into which the folded proteins are inseed. The chaperonin system mainly has Hsp60 and Hspl0.
