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
ribXTranscriptional regulator; Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes; Belongs to the NrdR family. (171 aa)    
Predicted Functional Partners:
ribD
AMP deaminase / 5-amino-6-(5-phosphoribosylamino)uracil reductase; 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.
  
  
 0.937
glyA
Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.

azo0059
Conserved hypothetical secreted protein. Homology to rsc3030 of R. solanacearum of 48% (sprot|YU30_RALSO) Pfam: Alpha-2-macroglobulin family Nterminal region (PF01835, PF07703) signal peptide no TMHs; Conserved hypothetical protein.
    
   0.679
ribAB
GTP cyclohydrolase II; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; Belongs to the DHBP synthase family.
    
 0.658
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
     
 0.584
azo2219
Conserved hypothetical membrane protein. Homology to cbiL of Actinobacillus pleuropneumoniae of 39% (gi|5733705|gb|AAD49725.1|(NBCI ENTREZ)). Signal P reproting signal peptide present. TMHMM reporting TMH present; Conserved hypothetical protein.
    
   0.578
nadE
NAD(+) synthase (glutamine-hydrolyzing); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
 
   
 0.522
birA
biotin--[acetyl-CoA-carboxylase] ligase; BirA bifunctional protein [Includes: Biotin operon repressor; Biotin--[acetyl-CoA-carboxylase] synthetase (EC 6.3.4.15) (Biotin--protein ligase)]. birA acts both as a biotin-operon repressor and as the enzyme that synthesizes the corepressor, acetyl-coa:carbon- dioxide ligase. this protein also activates biotin to form biotinyl-5'-adenylate and transfers the biotin moiety to biotin-accepting proteins. InterPro: Biotin--acetyl-CoA-carboxylase ligase birA_ligase: biotin--acetyl-CoA-carboxyla; Specificity unclear.
     
 0.463
nadD
Nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).
 
   
 0.463
lexA
Repressor LexA; 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.
