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

slyDFKBP-type peptidyl prolyl cis-trans isomerase (rotamase); Folding helper with both chaperone and peptidyl-prolyl cis- trans isomerase (PPIase) activities. Chaperone activity prevents aggregation of unfolded or partially folded proteins and promotes their correct folding. PPIases catalyze the cis-trans isomerization of Xaa- Pro bonds of peptides, which accelerates slow steps of protein folding and thus shortens the lifetime of intermediates. Both strategies lower the concentration of intermediates and increase the productivity and yield of the folding reaction. SlyD could be involved in [...] (196 aa)    
Predicted Functional Partners:
hypB
GTP hydrolase involved in nickel liganding into hydrogenases; Involved in the maturation of [NiFe] hydrogenases. Required for nickel insertion into the metal center of the hydrogenase. Exhibits a low intrinsic GTPase activity, which is essential for nickel insertion. In the presence of GDP, nickel, but not zinc, is transferred from the HypB GTPase domain (G-domain) to HypA. Belongs to the SIMIBI class G3E GTPase family. HypB/HupM subfamily.
    
 0.993
hycE
Large subunit of hydrogenase 3 (part of FHL complex); Protein involved in fermentation and anaerobic respiration; Belongs to the complex I 49 kDa subunit family.
   
 
 0.941
hypA
Protein involved in nickel insertion into hydrogenases 3; Involved in the maturation of [NiFe] hydrogenases. Required for nickel insertion into the metal center of the hydrogenase. Mediates transfer of nickel, but not zinc, from the low-affinity metal-binding site in the GTPase domain of HypB to HypA. HypA is involved in maturation of hydrogenase 3. It may partially substitute for the function of HybF and vice versa. May act as a scaffold for assembly of the nickel insertion proteins with the hydrogenase precursor protein after delivery of the iron center. Belongs to the HypA/HybF family.
    
 
 0.923
ygcR
Putative flavoprotein; May play a role in a redox process.
      
 0.809
trxA
Thioredoxin 1; Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions.
   
 
 0.779
tig
Peptidyl-prolyl cis/trans isomerase (trigger factor); Involved in protein export. Acts as a chaperone by maintaining the newly synthesized secretory and non-secretory proteins in an open conformation. Binds to 3 regions of unfolded substrate PhoA, preferring aromatic and hydrophobic residues, keeping it stretched out and unable to form aggregates. Binds to nascent polypeptide chains via ribosomal protein L23. Functions as a peptidyl-prolyl cis-trans isomerase in vitro, this activity is dispensible in vivo for chaperone activity. Belongs to the FKBP-type PPIase family. Tig subfamily.
   
  
 0.766
fkpA
FKBP-type peptidyl-prolyl cis-trans isomerase (rotamase); PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides.
   
  
 0.766
rpsB
30S ribosomal subunit protein S2; Required for ribosomal protein S1 to bind to the 30S subunit.
   
 
 0.744
surA
Peptidyl-prolyl cis-trans isomerase (PPIase); Chaperone involved in the correct folding and assembly of outer membrane proteins, such as OmpA, OmpF and LamB. Recognizes specific patterns of aromatic residues and the orientation of their side chains, which are found more frequently in integral outer membrane proteins. May act in both early periplasmic and late outer membrane- associated steps of protein maturation. Essential for the survival of E.coli in stationary phase. Required for pilus biogenesis.
   
  
 0.711
dnaK
Chaperone Hsp70, with co-chaperone DnaJ; Plays an essential role in the initiation of phage lambda DNA replication, where it acts in an ATP-dependent fashion with the DnaJ protein to release lambda O and P proteins from the preprimosomal complex. DnaK is also involved in chromosomal DNA replication, possibly through an analogous interaction with the DnaA protein. Also participates actively in the response to hyperosmotic shock.
