This pathway responds to cell envelope disturbances and increases the expression of periplasmic protein folding and degradation factors. While the molecular function of the NlpE protein is unknown, it may be involved in detecting bacterial adhesion to abiotic surfaces. In Escherichia coli and Salmonella typhi, NlpE is also known to confer copper tolerance in copper-sensitive strains of Escherichia coli, and may be involved in copper efflux and delivery of copper to copper-dependent enzymes [2].

While the molecular function of the NlpE protein is unknown, it may be involved in detecting bacterial adhesion to abiotic surfaces. In Escherichia coli and Salmonella typhi, NlpE is also known to confer copper tolerance in copper-sensitive strains of Escherichia coli, and may be involved in copper efflux and delivery of copper to copper-dependent enzymes [2]. This domain is found at the C-terminus of the NlpE protein [3].
