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

abbARegulator of AbrB repressor; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type r: regulator. (65 aa)    
Predicted Functional Partners:
abrB
Transcriptional regulator for transition state genes; 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; To B.subtilis Abh and SpoVT.

veg
Conserved hypothetical protein; Stimulates biofilm formation via transcriptional activation of extracellular matrix genes. Acts by repressing SinR activity, independently of the SinI, SlrA and SlrR pathways. Could also be involved in the regulation of other genes during biofilm and spore formation.
   
  
 0.754
mstX
Atypical membrane-integrating protein (Mistic protein); Chaperone that facilitates the production and integration of integral membrane proteins into the bacterial lipid bilayer.
      
 0.687
sinI
Antagonist of SinR; Acts as an antagonist to SinR. SinI prevents SinR from binding to its target sequence on the gene for AprE.
   
  
 0.682
ykuK
Putative RNAse; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
  
    0.589
spo0A
Response regulator; 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).
   
  
 0.510
ykuL
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; PubMedId: 11985717.
  
    0.491
slrA
Anti-repressor of SlrR; Required specifically for induction of eps and yqxM operons by antagonizing SinR. Regulates SlrR activity. Controls the initiation of biofilm formation.
      
 0.483
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 [...]
