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

RCIX834Nucleoside-triphosphatase (Ham1-like); 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. (189 aa)    
Predicted Functional Partners:
guaA-2
GMP synthase, glutamine-hydrolyzing; Catalyzes the synthesis of GMP from XMP.
 
 
 0.959
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.
  
 0.947
guaB-1
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.
  
 0.946
guaA-1
GMP synthase, glutamine-hydrolyzing; Catalyzes the synthesis of GMP from XMP.
 
 
 0.944
surE
Nucleoside 5'-monophosphate phosphohydrolase (survival protein); Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.910
RCIX2278
Putative metallophosphoesterase.
  
  
 0.904
rrp41p
Putative exosome complex exonuclease 1; Catalytic component of the exosome, which is a complex involved in RNA degradation. Has 3'->5' exoribonuclease activity. Can also synthesize heteropolymeric RNA-tails.
  
    0.689
rpl26e
50S ribosomal protein L26E; Stimulates transcription elongation; Belongs to the archaeal Spt5 family.
   
    0.645
RCIX1510
Dihydropteroate synthase-like conserved protein (FolP-like).
  
  
 0.639
thyA
Putative thymidylate synthase.
  
  
 0.627
