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

nrdBRibonucleoside-diphosphate reductase 1, beta subunit, ferritin-like protein; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R2 contains the tyrosyl radical required for catalysis; Belongs to the ribonucleoside diphosphate reductase small chain family. (376 aa)    
Predicted Functional Partners:
nrdA
Ribonucleoside-diphosphate reductase 1, alpha subunit; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R1 contains the binding sites for both substrates and allosteric effectors and carries out the actual reduction of the ribonucleotide. It also provides redox-active cysteines.
 0.999
nrdE
Ribonucleoside-diphosphate reductase 2, alpha subunit; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R1E contains the binding sites for both substrates and allosteric effectors and carries out the actual reduction of the ribonucleotide; Belongs to the ribonucleoside diphosphate reductase large chain family.
 
 0.997
yfaE
Uncharacterized ferredoxin-like protein YfaE; Ferredoxin involved with ribonucleotide reductase diferric-tyrosyl radical (Y*) cofactor maintenance.
 
  
 0.993
nrdI
NrdEF cluster assembly flavodoxin; Probably involved in ribonucleotide reductase function. Belongs to the NrdI family.
  
 
 0.965
nrdF
Ribonucleoside-diphosphate reductase 2, beta subunit, ferritin-like protein; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R2F contains the tyrosyl radical required for catalysis; Belongs to the ribonucleoside diphosphate reductase small chain family.
  
  
0.938
ndk
Nucleoside diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate.
     
 0.933
cmk
Cytidylate kinase; ATP, dATP, and GTP are equally effective as phosphate donors. CMP and dCMP are the best phosphate acceptors. Belongs to the cytidylate kinase family. Type 1 subfamily.
    
 0.928
nrdD
Anaerobic ribonucleoside-triphosphate reductase; Catalyzes the conversion of ribonucleotides into deoxyribonucleotides, which are required for DNA synthesis and repair. Belongs to the anaerobic ribonucleoside-triphosphate reductase family.
  
  
 0.926
adk
Adenylate kinase; Catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. Plays an important role in cellular energy homeostasis and in adenine nucleotide metabolism; Belongs to the adenylate kinase family.
   
 
 0.920
tmk
Thymidylate kinase; Catalyzes the reversible phosphorylation of deoxythymidine monophosphate (dTMP) to deoxythymidine diphosphate (dTDP), using ATP as its preferred phosphoryl donor. Situated at the junction of both de novo and salvage pathways of deoxythymidine triphosphate (dTTP) synthesis, is essential for DNA synthesis and cellular growth; Belongs to the thymidylate kinase family.
