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.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

fecI_2RNA polymerase sigma factor FecI; Member of the extracytoplasmic function sigma factors which are active under specific conditions; binds with the catalytic core of RNA polymerase to produce the holoenzyme and directs bacterial core RNA polymerase to specific promoter elements to initiate transcription; this sigma factor regulates the genes for iron dicitrate transport; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the sigma-70 factor family. ECF subfamily. (173 aa)    
Predicted Functional Partners:
AKL36875.1
Iron dicitrate transport regulator FecR; With FecA forms the FecAR signal transduction system; ferric citrate binds FecA and transmits a signal across the outer membrane to FecR. FecR transmits a signal across the cytoplasmic membrane and activates the sigma 70 protein FecI that directs the RNA polymerase to express the fecABCDE operon; Derived by automated computational analysis using gene prediction method: Protein Homology.

rseA
anti-RNA polymerase sigma factor SigE; An anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-E (RpoE). ECF sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis (RIP). RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut periplasmically (site-1 protease, S1P, DegS), then within the membrane itself (site-2 protease, S2P, RseP), while cytoplasmic protea [...]
