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

csaAMolecular chaperone; Can suppress growth and secretion defects in E.coli secA and secB mutants. Probably a molecular chaperone for exported proteins or may act by stabilizing the SecA protein. (110 aa)    
Predicted Functional Partners:
secA
Translocase binding subunit (ATPase); Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane; Belongs to the SecA family.
     
 0.930
pheS
phenylalanyl-tRNA synthetase (alpha subunit); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the class-II aminoacyl-tRNA synthetase family. Phe-tRNA synthetase alpha subunit type 1 subfamily.
  
 
 0.897
yobQ
Putative transcriptional regulator (AraC/XylS family); Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative regulator.
  
    0.800
secDF
Protein-export membrane protein; Required for efficient translocation of secretory pre- proteins under conditions of hypersecretion but is not required for the release of mature proteins from the membrane. In the N-terminal section; belongs to the SecD/SecF family. SecD subfamily.
  
 
 0.798
dnaJ
Co-factor of molecular chaperone; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP-dependent interactions betwe [...]

yobR
Putative acetyltransferase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the acetyltransferase family.
 
    0.681
tig
Prolyl isomerase (trigger factor); 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 (By similarity). Belongs to the FKBP-type PPIase family. Tig subfamily.
  
  
 0.643
oxaAB
Sec-independent factor for membrane protein insertion (YidC/SpoIIIJ family); Required for the insertion and/or proper folding and/or complex formation of integral membrane proteins into the membrane. Involved in integration of membrane proteins that insert both dependently and independently of the Sec translocase complex, as well as at least some lipoproteins (By similarity). Also involved in protein secretion processes. It has an overlapping, although partly distinct, function compared to SpoIIIJ(MisCB).
  
  
 0.622
nnrA
NAD(P)H dehydratase; Catalyzes the dehydration of the S-form of NAD(P)HX at the expense of ADP, which is converted to AMP. Together with NAD(P)HX epimerase, which catalyzes the epimerization of the S- and R-forms, the enzyme allows the repair of both epimers of NAD(P)HX, a damaged form of NAD(P)H that is a result of enzymatic or heat-dependent hydration.
      0.614
ffh
Signal recognition particle-like (SRP) GTPase; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY. Interaction with FtsY leads to the transfer of the RNC complex to the Sec translocase for insertion into the membrane, the hydrolysis of GTP by both Ffh and FtsY, and the dissociation of the SRP-FtsY complex into the individua [...]
