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

KXB90678.1Non-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. (212 aa)    
Predicted Functional Partners:
murI
Glutamate racemase; Provides the (R)-glutamate required for cell wall biosynthesis.
 
 
  0.959
guaA
GMP synthase domain protein; Catalyzes the synthesis of GMP from XMP.
 
 
 0.943
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.
  
 0.920
xpt
Xanthine 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.
   
 0.888
KXB93143.1
KEGG: med:MELS_0139 2.5e-68 hypoxanthine phosphoribosyltransferase; K00760 hypoxanthine phosphoribosyltransferase; Psort location: Cytoplasmic, score: 9.97; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
   
 
 0.847
KXB90679.1
Hypothetical protein; KEGG: cai:Caci_5966 3.8e-12 asparagine synthase K01953.
       0.791
KXB90680.1
Hypothetical protein.
       0.744
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.
 
 
 0.728
KXB90731.1
KEGG: med:MELS_1142 2.7e-64 GTP cyclohydrolase I; K01495 GTP cyclohydrolase I; Psort location: Cytoplasmic, score: 9.97.
  
 
 0.726
KXB92776.1
Phosphodiesterase family protein; KEGG: cbm:CBF_1049 9.4e-46 phosphodiesterase K07095.
