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

SDD13097.1Stage V sporulation protein B. (529 aa)    
Predicted Functional Partners:
SDD98238.1
Uncharacterized protein, UPF0297 family; Belongs to the UPF0297 family.
  
     0.765
purA
Adenylosuccinate synthetase; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.
       0.749
SDE02043.1
tRNA (adenine22-N1)-methyltransferase.
  
     0.662
SDD09816.1
Hypothetical protein; Might take part in the signal recognition particle (SRP) pathway. This is inferred from the conservation of its genetic proximity to ftsY/ffh. May be a regulatory protein.
  
     0.618
SDD13373.1
Uncharacterized conserved protein YloU, alkaline shock protein (Asp23) family.
 
     0.601
polC
DNA polymerase-3 subunit alpha; Required for replicative DNA synthesis. This DNA polymerase also exhibits 3' to 5' exonuclease activity.
  
    0.585
whiA
Hypothetical protein; Involved in cell division and chromosome segregation.
  
     0.565
SDD13054.1
Bacterial nucleoid protein Hbs; Histone-like DNA-binding protein which is capable of wrapping DNA to stabilize it, and thus to prevent its denaturation under extreme environmental conditions.
       0.557
SDD13001.1
Ribosomal 50S subunit-recycling heat shock protein, contains S4 domain.
  
    0.522
SDD95214.1
Hypothetical protein.
  
     0.518
