== Function ==
 +
[https://www.uniprot.org/uniprot/RPOE_ECOLI RPOE_ECOLI] Sigma factors are initiation factors that promote the attachment of RNA polymerase (RNAP) to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma-E controls the envelope stress response, responding to periplasmic protein stress, increased levels of periplasmic lipopolysaccharide (LPS) as well as heat shock and oxidative stress; it controls protein processing in the extracytoplasmic compartment. The 90 member regulon consists of the genes necessary for the synthesis and maintenance of both proteins and LPS of the outer membrane.<ref>PMID:7889935</ref> <ref>PMID:7889934</ref> <ref>PMID:2691330</ref> <ref>PMID:9159522</ref> <ref>PMID:9159523</ref> <ref>PMID:16336047</ref>
