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
XptKEGG: stf:Ssal_00834 3.5e-94 xpt; xanthine phosphoribosyltransferase; K03816 xanthine phosphoribosyltransferase; Psort location: Cytoplasmic, score: 9.97. (193 aa)    
Predicted Functional Partners:
guaA
GMP synthase domain protein; Catalyzes the synthesis of GMP from XMP.
 
 0.985
KXU57550.1
Xanthine permease; KEGG: apb:SAR116_1372 1.6e-59 xanthine/uracil permease K03458; Psort location: CytoplasmicMembrane, score: 10.00.
  
 0.981
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.
  
 
 0.954
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.946
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
     
 0.927
Hpt
KEGG: ssr:SALIVB_0012 1.3e-89 hpt; hypoxanthine-guanine phosphoribosyltransferase K00760; Psort location: Cytoplasmic, score: 9.97.
   
 0.926
deoD
KEGG: stf:Ssal_01032 4.4e-119 deoD; purine nucleoside phosphorylase; K03784 purine-nucleoside phosphorylase; Psort location: Cytoplasmic, score: 9.97.
    
 0.908
PurL
KEGG: stj:SALIVA_0041 0. purL; phosphoribosylformylglycinamidine synthase II (FGAM synthase) (FGAMS) (Formylglycinamide ribotide amidotransferase) (FGARAT) (Formylglycinamide ribotide synthetase); Psort location: Cytoplasmic, score: 9.97.
