== Function ==
[https://www.uniprot.org/uniprot/DEGS_ECOLI DEGS_ECOLI] When heat shock or other environmental stresses disrupt protein folding in the periplasm, DegS senses the accumulation of unassembled outer membrane porins (OMPs) and then initiates RseA (anti sigma-E factor) degradation by cleaving it in its periplasmic domain, making it an attractive substrate for subsequent cleavage by RseP. This cascade that ultimately leads to the sigma-E-driven expression of a variety of factors dealing with folding stress in the periplasm and OMP assembly.<ref>PMID:12183369</ref> <ref>PMID:19695325</ref>
