Abstract

The abnormal accumulation of misfolded proteins outside the plasma (cytoplasmic or inner) membrane up-regulates the synthesis of a class of envelope-localized catalysts of protein folding and degradation. The pathway for this transmembrane signalling is mediated by the CpxR-CpxA two-component phospho-relay mechanism.
