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

ydcGConserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; Belongs to the UPF0310 family. (146 aa)    
Predicted Functional Partners:
ydcF
Hypothetical protein; Evidence 5: No homology to any previously reported sequences.
  
  
 0.992
ydcH
Putative transcriptional regulator; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative regulator.
 
  
 0.991
rsbX
Serine phosphatase; Negative regulator of sigma-B activity. Dephosphorylates RsbS. Plays a role both in maintaining low sigma-B activity during growth and in reestablishing prestress sigma-B activity after induction. Could have a negative feedback role by indirectly communicating sigma-B protein levels.
  
  
 0.629
ydcI
Putative RNA helicase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
  
    0.541
yhjM
Transcriptional regulator of the ntd operon; Positively regulates the ntdABC operon and negatively regulates its own transcription. Binds to NTD to induce ntdABC transcription.
      
 0.480
ydcK
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; Belongs to the SprT family.
  
    0.449
rsbV
Anti-anti-sigma factor (antagonist of RsbW); Positive regulator of sigma-B activity. Non-phosphorylated RsbV binds to RsbW, preventing its association with sigma-B. When phosphorylated, releases RsbW, which is then free to complex with and inactivate sigma-B.
  
    0.426
rsbW
Switch protein/serine kinase and anti-sigma factor (inhibitory sigma-B binding protein); Negative regulator of sigma-B activity. Phosphorylates and inactivates its specific antagonist protein, RsbV. Upon phosphorylation of RsbV, RsbW is released and binds to sigma-B, thereby blocking its ability to form an RNA polymerase holoenzyme (E-sigma-B).
  
    0.426
sigB
RNA polymerase sigma-37 factor (sigma(B)); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Sigma B is not essential for sporulation; rather it is required for maximal expression of ctc and csbA which are transcribed in the early stationary phase under conditions inimical to sporulation. May play a role in the ability of the bacterium to adapt to various stresses but is not essential for its survival under these conditions. Positively regulates expression of its own operon; Belongs to the sigma-70 fac [...]

mbl
MreB-like morphogen; Forms membrane-associated dynamic filaments that are essential for cell shape determination. Acts by regulating cell wall synthesis and cell elongation, and thus cell shape. A feedback loop between cell geometry and Mbl localization may maintain elongated cell shape by targeting cell wall growth to regions of negative cell wall curvature (By similarity). Filaments rotate around the cell circumference in concert with the cell wall synthesis enzymes. The process is driven by the cell wall synthesis machinery and does not depend on Mbl polymerization. Organizes peptid [...]
