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

gcvRTranscriptional repressor, regulatory protein accessory to GcvA; Negative transcriptional regulator of the glycine cleavage system operon (GCV). Does not autoregulate its own expression. It is not yet known how GcvR acts as a repressor. It does not seem to bind DNA. It could interact with GcvA and suppress its activatory activity. (190 aa)    
Predicted Functional Partners:
gcvA
Glycine cleavage system transcriptional activator; Regulatory protein for the glycine cleavage system operon (gcv). Mediates activation of gcv by glycine and repression by purines. GcvA is negatively autoregulated. Binds to three sites upstream of the gcv promoter; Belongs to the LysR transcriptional regulatory family.

bcp
Peroxiredoxin; Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides and as sensor of hydrogen peroxide-mediated signaling events.
 
  
 0.957
dapA
Dihydrodipicolinate synthase; Catalyzes the condensation of (S)-aspartate-beta-semialdehyde [(S)-ASA] and pyruvate to 4-hydroxy-tetrahydrodipicolinate (HTPA). Belongs to the DapA family.
  
    0.726
gcvT
Aminomethyltransferase, tetrahydrofolate-dependent, subunit (T protein) of glycine cleavage complex; The glycine cleavage system catalyzes the degradation of glycine.
 
   
 0.705
bamC
BamABCDE complex OM biogenesis lipoprotein; Part of the outer membrane protein assembly complex (Bam), which is involved in assembly and insertion of beta-barrel proteins into the outer membrane. Nonessential member of the complex that stabilizes the interaction between the essential proteins BamA and BamD. Efficient substrate folding and insertion into the outer membrane requires all 5 subunits. A lateral gate may open between the first and last strands of the BamA beta-barrel that allows substrate to insert into the outer membrane; comparison of the structures of complete and nearly [...]

ybeL
DUF1451 family protein; Putative alpha helical protein.
  
     0.674
gcvP
Glycine decarboxylase, PLP-dependent, subunit P of glycine cleavage complex; The glycine cleavage system catalyzes the degradation of glycine. The P protein binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor; CO(2) is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein; Belongs to the GcvP family.
  
  
 0.668
dppA
Dipeptide/heme ABC transporter periplasmic binding protein; Dipeptide-binding protein of a transport system that can be subject to osmotic shock. DppA is also required for peptide chemotaxis; Belongs to the bacterial solute-binding protein 5 family.
   
  
 0.643
ftsL
Membrane bound cell division leucine zipper septum protein; 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. Can also mediate Zn(2+)-sensitivity probably by increasing the permeability of the inner membrane. Belongs to the FtsL family.
  
    0.604
yajD
HNH nuclease family protein; Belongs to the HNH nuclease family.
