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.

Score
pyrGCTP synthase; Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates. (557 aa)    
Predicted Functional Partners:
guaA
GMP synthase, glutamine-hydrolyzing; Catalyzes the synthesis of GMP from XMP.
  
 
 0.954
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.
  
 
 0.931
rpsB
Ribosomal protein S2; Identified by similarity to SP:P21464; match to protein family HMM PF00318; match to protein family HMM TIGR01011; Belongs to the universal ribosomal protein uS2 family.
  
 
 0.929
rpoB
DNA-directed RNA polymerase, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 
 0.913
maf
Septum formation protein MaF; Nucleoside triphosphate pyrophosphatase. May have a dual role in cell division arrest and in preventing the incorporation of modified nucleotides into cellular nucleic acids.
    
  0.903
sync_1265
Ribonucleotide reductase (Class II); Identified by match to protein family HMM TIGR02505.
     
 0.902
pnpA
Polyribonucleotide nucleotidyltransferase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction.
  
  
 0.856
argS
arginyl-tRNA synthetase; Identified by match to protein family HMM PF00750; match to protein family HMM PF03485; match to protein family HMM PF05746; match to protein family HMM TIGR00456.
  
  
 0.830
queE
Possible organic radical activating enzyme; Catalyzes the complex heterocyclic radical-mediated conversion of 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) to 7-carboxy-7- deazaguanine (CDG), a step common to the biosynthetic pathways of all 7-deazapurine-containing compounds.
     
 0.818
pyrH
Uridylate kinase; Catalyzes the reversible phosphorylation of UMP to UDP.
