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

Score
degQPleiotropic regulator; Stimulates the phosphotransfer from phospho-DegS to DegU. Affects protease and levansucrose production. (46 aa)    
Predicted Functional Partners:
comP
Two-component sensor histidine kinase; Sensor in the two-component regulatory system ComP/ComA involved in a major quorum response pathway that regulates the development of genetic competence. Plays a role in sporulation, at least partly interchangeable with that of SpoIIJ. Probably activates ComA by phosphorylation.
     
 0.950
degS
Two-component sensor histidine kinase; Member of the two-component regulatory system DegS/DegU, which plays an important role in the transition growth phase. Involved in the control of expression of different cellular functions, including production of degradative enzymes such as the neutral and alkaline proteases, flagellum formation and biofilm formation. Acts as both a protein kinase that undergoes autophosphorylation and subsequently transfers the phosphate to DegU, and a protein phosphatase that dephosphorylates phospho-DegU.
      
 0.920
comQ
Isoprenyl transferase (pre-ComX modification); Involved in the maturation of ComX, part of a major quorum- sensing system that regulates the development of genetic competence.
     
 0.861
degR
Activation of degradative enzymes (aprE, nprE, sacB) production or activity; Stabilizes the phosphorylated form of DegU, leading to enhanced production of levansucrase, alkaline protease, and neutral protease.
      
 0.849
capE
Factor required for polyglutamate synthesis; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type f: factor.
      
 0.758
srfAA
Surfactin synthetase; This protein is a multifunctional enzyme able to activate and polymerize the amino acids Leu, Glu, Asp and Val. Activation sites for these AA consist of individual domains.
      
 0.755
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.
      
 0.687
sacB
Levansucrase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
      
 0.682
capB
Capsular polyglutamate synthetase (ATP-dependent amide ligase); Catalyzes the biosynthesis of PGA (gamma-polyglutamic acid) from L-glutamate. Both the 44-kDa and the 33-kDa forms are required for PGA synthesis.
      
 0.681
comX
Competence pheromone precursor (pheromone peptide aa 46->55, geranyl-modified); Part of a major quorum-sensing system that regulates the development of genetic competence. Acts through the activation of the two-component regulatory system ComP/ComA composed of a sensor histidine kinase, ComP, and a response regulator, ComA, that regulates directly the transcription of over 20 genes. Transport through the membrane may involve Spo0K. Under certain conditions plays a role in sporulation.
