ADP-ATP exchange by the molecular chaperone Hsp70 is enhanced by several cochaperones. BAG5 consists of five BAG domains and associates with the nucleotide-binding domain (NBD) of Hsp70.

BD5 binding caused two different types of NBD conformational changes, which both disrupted the nucleotide-binding groove. In fact, BD5 reduced the affinity of the NBD for ADP.
