Your Input:
dnaKChaperone Hsp70; Acts as a chaperone. (638 aa)
dnaJHeat shock protein DnaJ; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion.
