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

gcvAGlycine 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. (305 aa)    
Predicted Functional Partners:
gcvR
Transcriptional 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.

ygdD
UPF0382 family inner membrane protein.
 
    0.978
rlmM
23S rRNA C2498 2'-O-ribose methyltransferase, SAM-dependent; Catalyzes the 2'-O-methylation at nucleotide C2498 in 23S rRNA. Modifies C2498 in naked 23S rRNA, but not in assembled 50S subunits or ribosomes.
 
    0.902
gcvT
Aminomethyltransferase, tetrahydrofolate-dependent, subunit (T protein) of glycine cleavage complex; The glycine cleavage system catalyzes the degradation of glycine.
      
 0.806
cysB
N-acetylserine-responsive cysteine regulon transcriptional activator; This protein is a positive regulator of gene expression for the cysteine regulon, a system of 10 or more loci involved in the biosynthesis of L-cysteine from inorganic sulfate. The inducer for CysB is N-acetylserine. CysB inhibits its own transcription.
  
   
 0.796
csdE
CsdA-binding activator; Stimulates the cysteine desulfurase activity of CsdA. Contains a cysteine residue (Cys-61) that acts to accept sulfur liberated via the desulfurase activity of CsdA. May be able to transfer sulfur to TcdA/CsdL. Seems to support the function of TcdA in the generation of cyclic threonylcarbamoyladenosine at position 37 (ct(6)A37) in tRNAs that read codons beginning with adenine. Does not appear to participate in Fe/S biogenesis; Belongs to the SufE family.
  
    0.754
fadR
Fatty acid metabolism regulon transcriptional regulator; Multifunctional regulator of fatty acid metabolism. Represses transcription of at least eight genes required for fatty acid transport and beta-oxidation including fadA, fadB, fadD, fadL and fadE. Activates transcription of at least three genes required for unsaturated fatty acid biosynthesis: fabA, fabB and iclR, the gene encoding the transcriptional regulator of the aceBAK operon encoding the glyoxylate shunt enzymes.
  
  
 0.662
metJ
Transcriptional repressor, S-adenosylmethionine-binding; This regulatory protein, when combined with SAM (S- adenosylmethionine) represses the expression of the methionine regulon and of enzymes involved in SAM synthesis. It is also autoregulated.
  
   
 0.646
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.
   
  
 0.612
yejL
UPF0352 family protein; Belongs to the UPF0352 family.
