Ases its substrates. After dissociation from Hsp70, the polypeptide chains fold into a functional three-dimensional architecture. A model has been proposed in which Hsp40 first recognizes and binds substrate polypeptides and then transfers them to Hsp70. However, in some cases, DnaK itself recognizes and binds to substrate polypeptides independent of DnaJ, as in the case of 32 (24). Because most o
