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

queCexsB protein; Catalyzes the ATP-dependent conversion of 7-carboxy-7- deazaguanine (CDG) to 7-cyano-7-deazaguanine (preQ(0)). Belongs to the QueC family. (232 aa)    
Predicted Functional Partners:
queE
Radical SAM domain protein; Catalyzes the complex heterocyclic radical-mediated conversion of 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) to 7-carboxy-7- deazaguanine (CDG), a step common to the biosynthetic pathways of all 7-deazapurine-containing compounds.

ACV23889.1
TIGRFAM: 6-pyruvoyl tetrahydropterin synthase; KEGG: hypothetical protein similar to 6-pyruvoyl tetrahydropterin synthase; K01737 6-pyruvoyl tetrahydrobiopterin synthase.
 
  
 0.996
crcB
CrcB protein; Important for reducing fluoride concentration in the cell, thus reducing its toxicity; Belongs to the CrcB (TC 9.B.71) family.
     
 0.861
tgtA
Archaeosine tRNA-ribosyltransferase; Exchanges the guanine residue with 7-cyano-7-deazaguanine (preQ0) at position 15 in the dihydrouridine loop (D-loop) of archaeal tRNAs; Belongs to the archaeosine tRNA-ribosyltransferase family.

tmk
KEGG: wpi:WPa_0905 thymidylate kinase; TIGRFAM: thymidylate kinase; PFAM: thymidylate kinase.

ACV24014.1
KEGG: dat:HRM2_45740 GlnA2; TIGRFAM: glutamine synthetase, type I; PFAM: glutamine synthetase catalytic region; glutamine synthetase beta-Grasp.
     
 0.576
cofC
2-phospho-L-lactate guanylyltransferase CofC; Guanylyltransferase that catalyzes the activation of phosphoenolpyruvate (PEP) as enolpyruvoyl-2-diphospho-5'-guanosine, via the condensation of PEP with GTP. It is involved in the biosynthesis of coenzyme F420, a hydride carrier cofactor; Belongs to the CofC family.
      
 0.560
nth
DNA-(apurinic or apyrimidinic site) lyase; DNA repair enzyme that has both DNA N-glycosylase activity and AP-lyase activity. The DNA N-glycosylase activity releases various damaged pyrimidines from DNA by cleaving the N-glycosidic bond, leaving an AP (apurinic/apyrimidinic) site. The AP-lyase activity cleaves the phosphodiester bond 3' to the AP site by a beta-elimination, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'- phosphate.
  
    0.545
nadK
ATP-NAD/AcoX kinase; Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP.
     
 0.527
ACV24364.1
PFAM: N-6 DNA methylase; restriction modification system DNA specificity domain; KEGG: wsu:WS1649 DNA methylase-type I restriction-modification system.
