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

xptXanthine phosphoribosyltransferase; Converts the preformed base xanthine, a product of nucleic acid breakdown, to xanthosine 5'-monophosphate (XMP), so it can be reused for RNA or DNA synthesis. (193 aa)    
Predicted Functional Partners:
guaA
GMP synthase (glutamine-hydrolyzing) domain protein; Catalyzes the synthesis of GMP from XMP.
  
 0.992
EDP27473.1
Purine nucleoside phosphorylase I, inosine and guanosine-specific; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate.
  
 
 0.969
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.966
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.
  
 
 0.966
hisE
phosphoribosyl-ATP diphosphatase; KEGG: sao:SAOUHSC_03008 9.1e-67 imidazole glycerol phosphate synthase subunit HisF, putative K01663; COG: COG0139 Phosphoribosyl-AMP cyclohydrolase; Psort location: Cytoplasmic, score:9.98; In the C-terminal section; belongs to the PRA-PH family.
  
 
 0.957
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
     
 0.952
hpt
KEGG: sco:SCO3405 5.4e-46 hprT, SCE9.12c; putative hypoxanthine phosphoribosyltransferase K00760; COG: COG0634 Hypoxanthine-guanine phosphoribosyltransferase; Psort location: Cytoplasmic, score:9.98; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
   
 0.942
rdgB
Non-canonical purine NTP pyrophosphatase, RdgB/HAM1 family; 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.
   
 0.937
EDP26286.1
Amidohydrolase family protein; KEGG: mma:MM2279 4.1e-55 N-ethylammeline chlorohydrolase K01564; COG: COG0402 Cytosine deaminase and related metal-dependent hydrolases; Psort location: Cytoplasmic, score:8.87.
     
 0.932
EDP26479.1
Aldehyde oxidase and xanthine dehydrogenase, molybdopterin binding domain protein; KEGG: eco:b2881 2.4e-123 xdhD, ygfN; possible hypoxanthine oxidase; COG: COG1529 Aerobic-type carbon monoxide dehydrogenase, large subunit CoxL/CutL homologs; Psort location: CytoplasmicMembrane, score:9.49.
