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

slrRHTH-type transcriptional regulator SlrR; Represses sigma(D)-dependent flagellar genes and activate the eps and yqxM operons. Repressor activity is regulated by SlrA. Controls the initiation of biofilm formation (152 aa)    
Predicted Functional Partners:
tapA
Uncharacterized protein YqxM; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type lp : lipoprotein
      
 0.956
slrA
Transcriptional regulator SlrA; Required specifically for induction of eps and yqxM operons by antagonizing SinR. Regulates SlrR activity. Controls the initiation of biofilm formation
      
 0.956
sipW
Signal peptidase I W; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e : enzyme; Belongs to the peptidase S26B family
  
   
 0.954
epsA
Uncharacterized protein YveK; Evidence 2b: Function of strongly homologous gene; Product type r : regulator
     
 0.951
sinI
Protein SinI; Acts as an antagonist to SinR. SinI prevents SinR from binding to its target sequence on the gene for AprE
      
 0.937
epsE
Putative glycosyltransferase EpsE; May be involved in the production of the exopolysaccharide (EPS) component of the extracellular matrix during biofilm formation. EPS is responsible for the adhesion of chains of cells into bundles. Required for biofilm maintenance
     
 0.888
ywcC
Uncharacterized HTH-type transcriptional regulator YwcC; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pr: putative regulator
  
   
 0.854
ymdB
2',3'-cyclic-nucleotide 2'-phosphodiesterase; Plays a central, regulatory role in the late adaptive responses and affects the levels of many genes. May act via regulation of cAMP levels. Decreases the expression of motility genes and induces genes involved in biofilm formation, by controlling the expression of SlrR. Required for formation of intercellular nanotubes that bridge neighboring cells to allow molecular exchange. Plays a key role in directing the early stages of colony development. In vitro, has a metal-dependent phosphodiesterase activity against 2',3'- cAMP and 2',3'-cGMP. [...]
     
 0.852
spo0A
Stage 0 sporulation protein A; May play the central regulatory role in sporulation. It may be an element of the effector pathway responsible for the activation of sporulation genes in response to nutritional stress. Spo0A may act in concert with Spo0H (a sigma factor) to control the expression of some genes that are critical to the sporulation process. Repressor of abrB, activator of the spoIIa operon. Binds the DNA sequence 5'-TGNCGAA-3' (0A box)
      
 0.832
abrB
Transition state regulatory protein AbrB; Ambiactive repressor and activator of the transcription of genes expressed during the transition state between vegetative growth and the onset of stationary phase and sporulation. It controls the expression of genes spovG and tycA. AbrB binds to the tycA promoter region at two A- and T-rich sites, it may be the sole repressor of tycA transcription
