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

dutdUTP pyrophosphatase (Deoxyuridine 5'-triphosphate nucleotidohydrolase); This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA; Belongs to the dUTPase family. (148 aa)    
Predicted Functional Partners:
thyA
Thymidylate synthase; Catalyzes the reductive methylation of 2'-deoxyuridine-5'- monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor and reductant in the reaction, yielding dihydrofolate (DHF) as a by- product. This enzymatic reaction provides an intracellular de novo source of dTMP, an essential precursor for DNA biosynthesis.

tdk
Similar to Q87QJ8 Thymidine kinase from Vibrio parahaemolyticus (192 aa). FASTA: opt: 629 Z-score: 820.6 E(): 8.2e-38 Smith-Waterman score: 629; 46.465identity in 198 aa overlap.
   
 
 0.963
nupC2
Thymidylate kinase; Phosphorylation of dTMP to form dTDP in both de novo and salvage pathways of dTTP synthesis; Belongs to the thymidylate kinase family.
  
 
 0.939
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; Belongs to the NDK family.
   
 
 0.932
dcd
Deoxycytidine triphosphate deaminase; Catalyzes the deamination of dCTP to dUTP.
  
 
 0.918
cdsA
Similar to Q88MH5 Phosphatidate cytidylyltransferase from Pseudomonas putida (271 aa). FASTA: 398 opt: 534 Z-score: 626.6 E(): 5.2e-27 Smith-Waterman score: 536; 35.926 identity in 270 aa overlap; Belongs to the CDS family.

dnaN
DNA polymerase III, beta chain; Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta chain is required for initiation of r [...]

pgsA
Similar to Q8XFD0 Phosphotidylglycerophosphate synthetase from Salmonella typhi (182 aa). FASTA: opt: 575 Z-score: 728.4 E(): 1.1e-32 Smith-Waterman score: 618; 50.000identity in 188 aa overlap; Belongs to the CDP-alcohol phosphatidyltransferase class-I family.
  
    0.783
uppS
Undecaprenyl pyrophosphate synthetase; Catalyzes the sequential condensation of isopentenyl diphosphate (IPP) with (2E,6E)-farnesyl diphosphate (E,E-FPP) to yield (2Z,6Z,10Z,14Z,18Z,22Z,26Z,30Z,34E,38E)-undecaprenyl diphosphate (di- trans,octa-cis-UPP). UPP is the precursor of glycosyl carrier lipid in the biosynthesis of bacterial cell wall polysaccharide components such as peptidoglycan and lipopolysaccharide.
  
    0.749
pyrH
Uridylate kinase; Catalyzes the reversible phosphorylation of UMP to UDP.
