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

Score
nrdRConserved hypothetical protein; Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes; Belongs to the NrdR family. (151 aa)    
Predicted Functional Partners:
cobN
Putative cobalamin biosynthesis related protein; Similar to Mycobacterium tuberculosis CobN or Rv2062c or MT2121 or MTCY49.01c or MTV019.03 SWALL:AAK46401 (EMBL:AL021922) (1195 aa) fasta scores: E(): 0, 62.22% id in 1215 aa, and to Methanococcus jannaschii hypothetical protein MJ0908 SWALL:Q58318 (EMBL:U67534) (1232 aa) fasta scores: E(): 5.1e-109, 36.48% id in 1258 aa.
      
 0.816
nrdE
Ribonucleoside-diphosphate reductase alpha chain; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides.
     
 0.624
ribD
Putative riboflavin biosynthesis protein; Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'- phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'- phosphate; In the C-terminal section; belongs to the HTP reductase family.
  
  
 0.603
lexA
Transcriptional repressor; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. In the presence of single-stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair.
 
   
 0.597
cobK
precorrin-6X reductase; Similar to Rhodococcus erythropolis precorrin-6X reductase CobK SWALL:COBK_RHOER (SWALL:Q53139) (248 aa) fasta scores: E(): 1.6e-41, 50% id in 244 aa, and to Mycobacterium tuberculosis precorrin-6X reductase CobK or Rv2070c or MT2130 or MTCY49.09c SWALL:COBK_MYCTU (SWALL:Q10680) (244 aa) fasta scores: E(): 1.2e-36, 47.54% id in 244 aa.
      
 0.569
ribA
Riboflavin biosynthesis protein RibA; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; In the C-terminal section; belongs to the GTP cyclohydrolase II family.
     
 0.561
nrdF2
