Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:

Node Content
empty nodes:

tolCTransport channel; Outer membrane channel, which is required for the function of several efflux systems such as AcrAB-TolC, AcrEF-TolC, EmrAB-TolC and MacAB-TolC.

rpoERNA polymerase sigma E factor; 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 me [...] (191 aa)
acrDAminoglycoside/multidrug efflux system; Participates in the efflux of aminoglycosides. Confers resistance to a variety of these substances. Belongs to the resistance-nodulation-cell division (RND) (TC 2.A.6) family. (1037 aa)
rcsCHybrid sensory kinase in two-component regulatory system with RcsB and YojN; Component of the Rcs signaling system, which controls transcription of numerous genes. RcsC functions as a membrane- associated protein kinase that phosphorylates RcsD in response to environmental signals. The phosphoryl group is then transferred to the response regulator RcsB. RcsC has also phosphatase activity. The system controls expression of genes involved in colanic acid capsule synthesis, biofilm formation and cell division. (949 aa)
rcsBResponse regulator in two-component regulatory system with RcsC and YojN; Component of the Rcs signaling system, which controls transcription of numerous genes. RcsB is the response regulator that binds to regulatory DNA regions. Can function both in an RcsA-dependent or RcsA-independent manner. The system regulates expression of numerous genes, including genes involved in colanic acid capsule synthesis, biofilm formation, cell division and outer membrane proteins synthesis. Also involved, with GadE, in control of glutamate-dependent acid resistance, and, with BglJ, in derepression of [...] (216 aa)
rcsDPhosphotransfer intermediate protein in two-component regulatory system with RcsBC; Component of the Rcs signaling system, which controls transcription of numerous genes. RcsD is a phosphotransfer intermediate between the sensor kinase RcsC and the response regulator RcsB. It acquires a phosphoryl group from RcsC and transfers it to RcsB. The system controls expression of genes involved in colanic acid capsule synthesis, biofilm formation and cell division. (890 aa)

ecpRPutative transcriptional regulator for the ecp operon; Part of the ecpRABCDE operon, which encodes the E.coli common pilus (ECP). ECP is found in both commensal and pathogenic strains and plays a dual role in early-stage biofilm development and host cell recognition. Positively regulates the expression of the ecp operon (By similarity). Also represses expression of the flagellar master operon flhDC, and consequently prevents flagellum biosynthesis and motility.
