Abstract

Protein quality control is accomplished by inducing chaperones and proteases in response to an altered cellular folding state. In Escherichia coli, expression of chaperones and proteases is positively regulated by sigma32. Chaperone-mediated negative feedback control of sigma32 activity allows this ...
