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

nrdZProbable ribonucleoside-diphosphate reductase (large subunit) NrdZ (ribonucleotide reductase); Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides (By similarity). (692 aa)    
Predicted Functional Partners:
nrdF2
Ribonucleoside-diphosphate reductase subunit beta nrdF2; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. Two genes for this protein are present in M.tuberculosis; this is the active form. When coexpressed in E.coli with nrdE the 2 proteins complement a temperature-sensitive E.coli mutant; Belongs to the ribonucleoside diphosphate reductase small chain family.
  
 0.992
nrdF1
Ribonucleoside-diphosphate reductase subunit beta nrdF1; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides (By similarity). Two genes for this protein are present in M.tuberculosis; this is thought to not be the active form. When coexpressed in E.coli with nrdE the 2 proteins do not complement a temperature-sensitive E.coli mutant, whereas the other gene (nrdF2) does complement; Belongs to the ribonucleoside diphosphate reductase small chain family.
  
 0.989
nrdB
Ribonucleoside-diphosphate reductase (beta chain) NrdB (ribonucleotide reductase small chain); Probable oxidase that might be involved in lipid metabolism.
  
 0.987
Rv0038
Conserved protein; Rv0038, (MTCY10H4.38), len: 202 aa. Conserved protein, similar to many; Belongs to the UPF0301 (AlgH) family.
   
 0.969
tmk
Thymidylate kinase Tmk (dTMP kinase) (thymidylic acid kinase) (TMPK); 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. Has a broad specificity for nucleoside triphosphates, being highly active with ATP or dATP as phosphate donors, and less active with ITP, GTP, CTP and UTP; Belongs to the thymidylate kinase family.
  
 
 0.932
cmk
Cytidylate kinase Cmk (CMP kinase) (cytidine monophosphate kinase) (ck); Rv1712, (MTCI125.34), len: 230 aa. cmk, cytidylate kinase, highly similar to many e.g. KCY_ECOLI|P23863 cytidylate kinase from Escherichia coli (227 aa), FASTA scores: opt: 534, E (): 0, (40.3% identity in 221 aa overlap). Contains PS00017 ATP/GTP-binding site motif A (P-loop). Equivalent to Z95117|MLCB1351_2 from Mycobacterium leprae (223 aa) (73.5% identity in 226 aa overlap). Belongs to the cytidylate kinase family,subfamily 1.
  
 
 0.922
nrdE
Ribonucleoside-diphosphate reductase subunit alpha; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. When coexpressed in E.coli with nrdF2 the 2 proteins complement a temperature-sensitive E.coli mutant, however coexpression with nrdF1 does not complement. Belongs to the ribonucleoside diphosphate reductase large chain family.
  
 
0.915
adk
Adenylate kinase Adk (ATP-AMP transphosphorylase); 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. Has a broad specificity for nucleoside triphosphates, being highly active with ATP or dATP as phosphate donors, and less active with GTP or UTP.
  
 
 0.914
ndkA
Probable nucleoside diphosphate kinase NdkA (NDK) (NDP kinase) (nucleoside-2-P 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; Belongs to the NDK family.
  
 
 0.912
gmk
Probable guanylate kinase Gmk; Essential for recycling GMP and indirectly, cGMP.
