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

nrdDAnaerobic ribonucleoside-triphosphate reductase (nrdD); Catalyzes the conversion of ribonucleotides into deoxyribonucleotides, which are required for DNA synthesis and repair. Belongs to the anaerobic ribonucleoside-triphosphate reductase family. (707 aa)    
Predicted Functional Partners:
nrdG
Anaerobic ribonucleoside-triphosphate reductase activating protein (nrdG); Activation of anaerobic ribonucleoside-triphosphate reductase under anaerobic conditions by generation of an organic free radical, using S-adenosylmethionine and reduced flavodoxin as cosubstrates to produce 5'-deoxy-adenosine; Belongs to the organic radical-activating enzymes family.
 
 
 0.946
dut
Deoxyuridinetriphosphatase (dut); This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA; Belongs to the dUTPase family.
    
 0.810
nrdB
Ribonucleoside diphosphate reductase, beta chain (nrdB); Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides (By similarity).
  
 
 0.795
dcd
Deoxycytidine triphosphate deaminase (dcd); Catalyzes the deamination of dCTP to dUTP.
    
  0.771
mazG
mazG protein (mazG); Involved in the regulation of bacterial cell survival under conditions of nutritional stress. Regulates the MazE-MazF toxin- antitoxin (TA) system that mediates programmed cell death (PCD). This is achieved by lowering the cellular concentration of (p)ppGpp produced by RelA under amino acid starvation, thus protecting the cell from the toxicity of MazF. Reduction of (p)ppGpp can be achieved by direct degradation of (p)ppGpp or by degradation of NTPs, which are substrates for (p)ppGpp synthesis by RelA (By similarity); Belongs to the nucleoside triphosphate pyrophos [...]

nrdA
Ribonucleoside-diphosphate reductase, alpha chain (nrdA); Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides (By similarity).
  
 
 0.742
queE
Conserved hypothetical 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.

hisI
phosphoribosyl-AMP cyclohydrolase / phosphoribosyl-ATP pyrophosphohydrolase (hisIE); Similar to SP:P06989 GB:D43637 GB:U02072 GB:X03974 PID:41700 percent identity: 61.22; identified by sequence similarity; putative; In the C-terminal section; belongs to the PRA-PH family.
     
 0.657
cyaA
Adenylate cyclase (cyaA); Plays an essential role in competence development.
  
  
  0.639
HI_0521
Conserved hypothetical protein; Similar to GB:U14003 SP:P37342 PID:537220 GB:U00096 PID:1790840 percent identity: 40.88; identified by sequence similarity; putative; To E.coli YjjI.
