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
rdgBNon-canonical purine NTP pyrophosphatase RdgB; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family. (194 aa)    
Predicted Functional Partners:
guaA
GMP synthase (glutamine-hydrolyzing), C-terminal domain protein; Catalyzes the synthesis of GMP from XMP.
 
 
 0.978
guaB
Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
  
 0.933
CUS_4675
SH3 domain protein; Identified by match to protein family HMM PF01551; match to protein family HMM PF08239.
    
  0.826
ftsY
Signal recognition particle-docking protein FtsY; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Acts as a receptor for the complex formed by the signal recognition particle (SRP) and the ribosome-nascent chain (RNC).
     
 0.818
CUS_4678
Hypothetical protein; Identified by glimmer; putative.
  
 
 0.817
CUS_4616
Identified by match to protein family HMM PF00149; match to protein family HMM TIGR00040.
  
  
 0.804
folE
Putative GTP cyclohydrolase I; Identified by match to protein family HMM PF01227.
  
 
 0.775
hpt
Hypoxanthine phosphoribosyltransferase; Identified by match to protein family HMM PF00156; match to protein family HMM TIGR01203; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
   
 
 0.769
CUS_7347
Hydrolase, NUDIX family; Identified by match to protein family HMM PF00293; Belongs to the Nudix hydrolase family.
  
 
 0.756
purA
Adenylosuccinate synthase; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.
