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

yaaBConserved hypothetical protein; Regulates the biosynthesis of the extracellular matrix and the biofilm formation. May act as an enhancer of biofilm gene expression. Acts in parallel to the pathway that governs SinR derepression. (81 aa)    
Predicted Functional Partners:
recF
DNA repair and genetic recombination factor; The RecF protein is involved in DNA metabolism; it is required for DNA replication and normal SOS inducibility. RecF binds preferentially to single-stranded, linear DNA. It also seems to bind ATP. Is recruited to repair centers, foci that are the site of double- strand DNA break(s) after RecN and RecO; recruitment may depend on RecO.
  
    0.901
ylzA
Conserved hypothetical protein; Regulates the biosynthesis of the extracellular matrix and the biofilm formation. Activates the transcription of the matrix biosynthesis operons eps and tapA-sipW- tasA. Also activates expression of the opuA operon, involved in osmoprotection. Acts by binding specifically to the promoter region of the target genes. Acts in parallel to the pathway that governs SinR derepression. Required for endosporulation.
  
  
 0.880
slrR
Transcriptional regulator of autolysin genes; 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.
  
   
 0.856
antE
Hypothetical protein; Evidence 5: No homology to any previously reported sequences; PubMedId: 9864351.
      
 0.846
sinR
Master regulator of biofilm formation; Negative as well as positive regulator of alternate developmental processes that are induced at the end of vegetative growth in response to nutrient depletion. Binds to the alkaline protease (aprE) gene at two sites. Also acts as a repressor of the key sporulation gene spo0A. Negatively regulates transcription of the eps operon, which is responsible for the biosynthesis of an exopolysaccharide involved in biofilm formation; therefore it could govern the transition between a state in which bacteria swim or swarm and a state in which bacteria assemb [...]
  
   
 0.836
gyrB
DNA gyrase (subunit B); A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner.
  
    0.766
yaaA
Putative RNA binding protein; May assist in the assembly of the 50S subunit.
  
    0.763
tapA
Lipoprotein for biofilm formation; Required for biofilm formation. Required for the proper anchoring and polymerization of TasA amyloid fibers at the cell surface. Is also a minor component of TasA fibers.
      
 0.753
sipW
Type I signal peptidase; Required for the cleavage of the signal sequence of TasA and TapA, which are involved in biofilm formation. Belongs to the peptidase S26B family.
      
 0.591
sinI
Antagonist of SinR; Acts as an antagonist to SinR. SinI prevents SinR from binding to its target sequence on the gene for AprE.
