<prompt> All are true about chaperones exceptCause folding of proteinsAre lipid in natureMay have ATPase activityInclude heat shock proteins  <response>: chaperones are proteins that assist the covalent folding or unfolding and the assembly or disassembly of other macromolecular structures. Chaperones are present when the macromolecules perform their normal biological functions and have correctly completed the processes of folding andor assembly. The chaperones are concerned primarily with protein folding. The first protein to be called a chaperone assists the assembly of nucleosomes from folded histones and DNA and such assembly chaperones, especially in the nucleus, are concerned with the assembly of folded subunits into oligomeric structures Ref-Sathyanarayana 4e p387
