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

yfhAEBP family; similar to E. coli putative 2-component transcriptional regulator (AAC75607.1); Blastp hit to AAC75607.1 (444 aa), 95% identity in aa 1 - 444. (445 aa)    
Predicted Functional Partners:
yfhK
Putative sensory kinase in regulatory system; Similar to E. coli putative 2-component sensor protein (AAC75609.1); Blastp hit to AAC75609.1 (496 aa), 87% identity in aa 19 - 496.
 
 0.999
rpoN
Sigma N factor of RNA polymerase; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is responsible for the expression of enzymes involved in arginine catabolism. The open complex (sigma-54 and core RNA polymerase) serves as the receptor for the receipt of the melting signal from the remotely bound activator protein GlnG(NtrC).
 
 
 0.958
ygiY
Putative sensory histidine kinase in regulatory system; Member of a two-component regulatory system QseB/QseC. Activates the flagella regulon by activating transcription of FlhDC. May activate QseB by phosphorylation (By similarity).
   
 0.932
yfhG
Putative transcriptional regulator of two-component regulator protein (EBP familiiy); EBP family; similar to E. coli putative alpha helix protein (AAC75608.1); Blastp hit to AAC75608.1 (237 aa), 63% identity in aa 1 - 234.
  
  
 0.895
yhfA
Putative inner membrane protein; Similar to E. coli orf, hypothetical protein (AAC76381.1); Blastp hit to AAC76381.1 (134 aa), 94% identity in aa 1 - 134.

glnB
Regulatory protein (P-II) for nitrogen assimilation by glutamine synthetase (ATase); P-II indirectly controls the transcription of the glutamine synthetase gene (GlnA). P-II prevents NR-II-catalyzed conversion of NR- I to NR-I-phosphate, the transcriptional activator of GlnA. When P-II is uridylylated to P-II-UMP, these events are reversed. When the ratio of Gln to 2-ketoglutarate decreases, P-II is uridylylated to P-II-UMP, which causes the deadenylation of glutamine synthetase by GlnE, so activating the enzyme (By similarity).
  
 
 0.815
glnL
Sensory histidine kinase/phosphatase NtrB; Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Under conditions of nitrogen limitation, NtrB autophosphorylates and transfers the phosphoryl group to NtrC. In the presence of nitrogen, acts as a phosphatase that dephosphorylates and inactivates NtrC.

fliM
Flagellar biosynthesis protein; FliM is one of three proteins (FliG, FliN, FliM) that forms the rotor-mounted switch complex (C ring), located at the base of the basal body. This complex interacts with the CheY and CheZ chemotaxis proteins, in addition to contacting components of the motor that determine the direction of flagellar rotation (By similarity).

fliG
Flagellar biosynthesis protein; FliG is one of three proteins (FliG, FliN, FliM) that forms the rotor-mounted switch complex (C ring), located at the base of the basal body. This complex interacts with the CheY and CheZ chemotaxis proteins, in addition to contacting components of the motor that determine the direction of flagellar rotation (By similarity).
  
  
 0.649
flhA
Flagellar biosynthesis protein; Required for formation of the rod structure of the flagellar apparatus. Together with FliI and FliH, may constitute the export apparatus of flagellin.
