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
nrdRTranscriptional regulator, NrdR family protein; Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes; Belongs to the NrdR family. (158 aa)    
Predicted Functional Partners:
ribD
Riboflavin biosynthesis protein RibD; 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.
  
  
 0.628
psbT
Photosystem II reaction centre T protein superfamily protein; Seems to play a role in the dimerization of PSII. Belongs to the PsbT family.
       0.549
rpsA
Ribosomal protein S1; Identified by similarity to SP:P46228; match to protein family HMM PF00575.
 
     0.547
ribAB
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.
     
 0.537
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.
     
 0.498
psbB
Photosystem II P680 chlorophyll A apoprotein; One of the components of the core complex of photosystem II (PSII). It binds chlorophyll and helps catalyze the primary light- induced photochemical processes of PSII. PSII is a light-driven water:plastoquinone oxidoreductase, using light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation; Belongs to the PsbB/PsbC family. PsbB subfamily.
       0.496
sync_1079
Sensory box histidine kinase/response regulator; Identified by match to protein family HMM PF00072; match to protein family HMM PF00512; match to protein family HMM PF02518.
     
 0.487
gph
Haloacid dehalogenase/epoxide hydrolase family protein; Identified by match to protein family HMM PF00702; match to protein family HMM TIGR01549.
       0.441
cbiE/cbiT
Precorrin-6y C5,15-methyltransferase (decarboxylating), CbiE/T subunits; Identified by match to protein family HMM PF00590; match to protein family HMM TIGR02467; match to protein family HMM TIGR02469.
      
 0.420
sync_2911
Chloride transporter, chloride channel (ClC) family protein; Identified by match to protein family HMM PF00654.
