|mzrA||Modulator of EnvZ/OmpR regulon; Modulates the activity of the EnvZ/OmpR two-component regulatory system, probably by directly modulating EnvZ enzymatic activity and increasing stability of phosphorylated OmpR. Links the two-component systems CpxA/CpxR and EnvZ/OmpR. Belongs to the MzrA family. (127 aa)|| |
Predicted Functional Partners:
General envelope maintenance protein; May be a membrane transporter required for proton motive force (PMF)-dependent drug efflux. Required, with YghB, for the proper export of certain periplasmic amidases and, possibly, other Tat substrates. May play a role in determining membrane lipid composition. Belongs to the DedA family.

Sensory histidine kinase in two-component regulatory system with OmpR; Member of the two-component regulatory system EnvZ/OmpR involved in osmoregulation (particularly of genes ompF and ompC) as well as other genes. EnvZ functions as a membrane-associated protein kinase that phosphorylates OmpR in response to environmental signals; at low osmolarity OmpR activates ompF transcription, while at high osmolarity it represses ompF and activates ompC transcription. Also dephosphorylates OmpR in the presence of ATP. The cytoplasmic dimerization domain (CDD) forms an osmosensitive core; increa [...]

Response regulator in two-component regulatory system with EnvZ; Member of the two-component regulatory system EnvZ/OmpR involved in osmoregulation (particularly of genes ompF and ompC) as well as other genes. Plays a central role in both acid and osmotic stress responses. Binds to the promoter of both ompC and ompF; at low osmolarity it activates ompF transcription, while at high osmolarity it represses ompF and activates ompC transcription. Involved in acid stress response; this requires EnvZ but not OmpR phosphorylation. Phosphorylated by EnvZ; this stimulates OmpR's DNA-binding abi [...]

Response regulator in two-component regulatory system with CpxA; Response regulator member of the two-component regulatory system CpxA/CpxR which responds to envelope stress response by activating expression of downstream genes including cpxP, degP, dsbA and ppiA. Required for efficient binding of stationary phase cells to hydrophobic surfaces, part of the process of biofilm formation. Induced upon cell surface binding, subsequently induces genes it controls (cpxP, dsbA and spy, degP is only partially induced). Binds and activates transcription from the degP promoter ; binding is enhan [...]

Sensory histidine kinase in two-component regulatory system with CpxR; Histidine kinase member of the two-component regulatory system CpxA/CpxR which responds to envelope stress response by activating expression of downstream genes including cpxP, degP, dsbA and ppiA. Activates CpxR by phosphorylation; has autokinase, phosphotransferase and (in the presence of Mg(2+) and/or ATP or ADP) phosphatase activity. The kinase activity is inhibited by periplasmic accessory protein CpxP; proteolysis of CpxP relieves inhibition. Involved in several diverse cellular processes, including the functi [...]

DUF1469 family inner membrane protein.

Two-component system connector membrane protein, EvgSA to PhoQP; Connects the signal transduction between the two-component systems EvgS/EvgA and PhoQ/PhoP, by directly interacting with PhoQ and thus activating the PhoQ/PhoP system, in response to acid stress conditions; Belongs to the SafA family.
| || || || || || || ||0.544
Putative membrane-anchored secretion pathway M-type protein; Involved in a type II secretion system (T2SS, formerly general secretion pathway, GSP) for the export of folded proteins across the outer membrane.

DUF2884 family putative periplasmic protein.
| || || || || || || ||0.529
Outer membrane porin protein C; Forms pores that allow passive diffusion of small molecules across the outer membrane. (Microbial infection) A mixed OmpC-OmpF heterotrimer is the outer membrane receptor for toxin CdiA-EC536; polymorphisms in extracellular loops 4 and 5 of OmpC confer susceptibility to CdiA- EC536-mediated toxicity; Belongs to the Gram-negative porin family.
