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

cytRAnti-activator for CytR-CRP nucleoside utilization regulon; This protein negatively controls the transcription initiation of genes such as deoCABD, udp, and cdd encoding catabolizing enzymes and nupC, nupG, and tsx encoding transporting and pore-forming proteins. Binds cytidine and adenosine as effectors. (341 aa)    
Predicted Functional Partners:
crp
cAMP-activated global transcription factor, mediator of catabolite repression; A global transcription regulator. Complexes with cyclic AMP (cAMP) which allosterically activates DNA binding (to consensus sequence 5'-AAATGTGATCTAGATCACATTT-3') to directly regulate the transcription of about 300 genes in about 200 operons and indirectly regulate the expression of about half the genome. There are 3 classes of CRP promoters; class I promoters have a single CRP-binding site upstream of the RNA polymerase (RNAP)-binding site, whereas in class II promoters the single CRP- and RNAP-binding site [...]

udp
Uridine phosphorylase; Catalyzes the reversible phosphorylytic cleavage of uridine and deoxyuridine to uracil and ribose- or deoxyribose-1-phosphate. The produced molecules are then utilized as carbon and energy sources or in the rescue of pyrimidine bases for nucleotide synthesis.
   
  
 0.898
sxy
CRP-S-dependent promoter expression factor; Induces low levels of natural DNA uptake by inducing transcription of the competence genes (the CRP-S regulon) required for DNA transformation. Induction of the CRP-S regulon also requires Sxy- activated promoter (CRP-S), cAMP receptor protein (CRP) and cAMP. Induces CRP-S site-containing genes which are involved in genome maintenance and transcription or encoding transposases and toxin-antitoxin pairs.
      
 0.737
deoR
Deoxyribose-5-phosphate-inducible deoxyribose operon transcriptional repressor; This protein is one of the repressors that regulate the expression of deoCABD genes, which encode nucleotide and deoxy ribonucleotide catabolizing enzymes. It also negatively regulates the expression of nupG (a transport protein) and tsx (a pore-forming protein). The inducer is deoxyribose-5-phosphate.
      
 0.731
deoC
2-deoxyribose-5-phosphate aldolase, NAD(P)-linked; Catalyzes a reversible aldol reaction between acetaldehyde and D-glyceraldehyde 3-phosphate to generate 2-deoxy-D-ribose 5- phosphate. Can also catalyze the double aldol condensation of three acetaldehyde molecules, leading to the formation of 2,4,6-trideoxyhexose. Belongs to the DeoC/FbaB aldolase family. DeoC type 2 subfamily.
      
 0.704
gltB
Glutamate synthase, large subunit; Catalyzes the conversion of L-glutamine and 2-oxoglutarate into two molecules of L-glutamate.
    
 
 0.655
melR
Melibiose operon transcriptional regulator; Transcription activator for the expression of the melAB operon. MelR binds at two sites located upstream of the melAB transcription site.
   
  
 0.637
glcC
Glycolate-inducible glc operon transcriptional repressor; Transcriptional activator of the glcDEFGB operon which is associated with glycolate utilization, and encodes malate synthase G and the genes needed for glycolate oxidase activity. Also negatively regulates the transcription of its own gene. Glycolate acts as an effector, but GlcC can also use acetate as an alternative effector.
   
 
 0.574
ftsN
Essential cell division protein; Essential cell division protein that activates septal peptidoglycan synthesis and constriction of the cell. Acts on both sides of the membrane, via interaction with FtsA in the cytoplasm and interaction with the FtsQBL complex in the periplasm. These interactions may induce a conformational switch in both FtsA and FtsQBL, leading to septal peptidoglycan synthesis by FtsI and associated synthases (Probable). Required for full FtsI activity. Required for recruitment of AmiC to the septal ring. Belongs to the FtsN family.
  
  
 0.572
menA
1,4-dihydroxy-2-naphthoate octaprenyltransferase; Conversion of 1,4-dihydroxy-2-naphthoate (DHNA) to demethylmenaquinone (DMK). Attaches octaprenylpyrophosphate, a membrane-bound 40-carbon side chain to DHNA. The conversion of DHNA to DMK proceeds in three stages: the removal of the carboxyl group of DHNA as CO(2), the attachment of the isoprenoid side chain, and a quinol-to- quinone oxidation, which is thought to be spontaneous.
