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.

sspBSimilar to E. coli stringent starvation protein B (AAC76260.1); Blastp hit to AAC76260.1 (165 aa), 89% identity in aa 1 - 165. (166 aa)    
Predicted Functional Partners:
sspA
Stringent starvation protein A; Regulator of transcription; similar to E. coli regulator of transcription; stringent starvation protein A (AAC76261.1); Blastp hit to AAC76261.1 (212 aa), 98% identity in aa 1 - 211; Belongs to the GST superfamily.

clpX
Specificity component of clpA-clpP ATP-dependent serine protease, chaperone; ATP-dependent specificity component of the Clp protease. It directs the protease to specific substrates. Can perform chaperone functions in the absence of ClpP.
   
 
 0.881
rseA
Anti sigma E (sigma 24) factor, negative regulator; An anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-E (RpoE). ECF sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis (RIP). RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut periplasmically (site-1 protease, S1P, DegS), then within the membrane itself (site-2 protease, S2P, RseP), while cytop [...]

tig
Peptidyl-prolyl cis/trans isomerase; Involved in protein export. Acts as a chaperone by maintaining the newly synthesized protein in an open conformation. Functions as a peptidyl-prolyl cis-trans isomerase; Belongs to the FKBP-type PPIase family. Tig subfamily.
  
  
 0.784
smpA
Small membrane protein A; Part of the outer membrane protein assembly complex, which is involved in assembly and insertion of beta-barrel proteins into the outer membrane.
  
    0.772
ygbQ
Putative Septum formation initiator; Essential cell division protein. May link together the upstream cell division proteins, which are predominantly cytoplasmic, with the downstream cell division proteins, which are predominantly periplasmic.
  
    0.759
holA
Similar to E. coli DNA polymerase III, delta subunit (AAC73741.1); Blastp hit to AAC73741.1 (343 aa), 89% identity in aa 1 - 343.
  
    0.750
metG
Methionine tRNA synthetase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
  
  
 0.721
ybeC
Putative Sec-independent protein secretion pathway component; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. TatE shares overlapping functions with TatA; Belongs to the TatA/E family. TatE subfamily.
  
    0.716
cca
tRNA nucleotidyl transferase; Catalyzes the addition and repair of the essential 3'- terminal CCA sequence in tRNAs without using a nucleic acid template. Adds these three nucleotides in the order of C, C, and A to the tRNA nucleotide-73, using CTP and ATP as substrates and producing inorganic pyrophosphate. Also shows phosphatase, 2'-nucleotidase and 2',3'-cyclic phosphodiesterase activities. These phosphohydrolase activities are probably involved in the repair of the tRNA 3'-CCA terminus degraded by intracellular RNases.
