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

sppASignal peptide peptidase; Digestion of cleaved signal peptides (By similarity). Required for efficient processing of precursors under conditions of hyper-secretion. Has a preference for leucine-rich substrate peptides. Belongs to the peptidase S49 family. (335 aa)    
Predicted Functional Partners:
yteJ
Putative integral inner membrane protein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pm: putative membrane component.
 
  
 0.995
yvlC
Putative regulator (stress mediated); Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pr: putative regulator.
   
  
 0.913
yqeZ
Putative membrane bound hydrolase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
  
  
 0.792
ydbT
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
 
    0.765
dapB
(4S)-4-hydroxy-2,3,4, 5-tetrahydro-(2S)-dipicolinic acid (HTPA) dehydratase reductase; Catalyzes the conversion of 4-hydroxy-tetrahydrodipicolinate (HTPA) to tetrahydrodipicolinate.
  
  
 0.746
yckC
Putative integral inner membrane protein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pm: putative membrane component.
 
   
 0.745
sigW
RNA polymerase ECF(extracytoplasmic function)-type sigma factor W; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Sigma-W controls genes involved in response to cell envelope stress such as antimicrobial peptides , alkaline pH , transport processes and detoxification.
   
  
 0.730
yknY
Putative ABC transporter (ATP-binding protein); Part of an unusual four-component transporter, which is required for protection against the killing factor SdpC (sporulation- delaying protein).
   
    0.707
ydbS
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
  
    0.706
pbpE
Penicillin-binding protein 4*; Probably involved in peptidoglycan modification during cortex synthesis.
