STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.

regX3DNA-binding response regulator RegX3; Part of the two-component regulatory system SenX3/RegX3. Once phosphorylated by SenX3, activates the expression of several operons/genes involved in phosphate assimilation and metabolism, such as pstSCAB, phnDCE, and phoA. (225 aa)    
Predicted Functional Partners:
senX3
Sensor histidine kinase SenX3; Part of the two-component regulatory system SenX3/RegX3. Phosphorylates RegX3 under conditions of phosphate limitation. Probably does not itself sense phosphate concentrations, which may be relayed to SenX3 by the PstSCAB phosphate transporter system.
 
 0.999
mtrB
Sensor histidine kinase MtrB; Member of the two-component regulatory system MtrA/MtrB. Probably functions as a membrane-associated protein kinase that phosphorylates MtrA in response to environmental signals (By similarity). MtrB may be active only at septa where it promotes MtrA phosphorylation and MtrA regulon expression, probably playing a role in cell division.
 
 0.929
mprB
Sensor histidine kinase; Member of the two-component regulatory system MprB/MprA which contributes to maintaining a balance among several systems involved in stress resistance and is required for establishment and maintenance of persistent infection in the host. In response to environmental signals MprB acts as both a membrane-associated protein kinase that undergoes autophosphorylation and subsequently transfers the phosphate to MprA, and a protein phosphatase that dephosphorylates phospho-MprA (By similarity).
