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.

Score
KXA30374.1Non-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. (194 aa)    
Predicted Functional Partners:
rph
tRNA nucleotidyltransferase; Phosphorolytic 3'-5' exoribonuclease that plays an important role in tRNA 3'-end maturation. Removes nucleotide residues following the 3'-CCA terminus of tRNAs; can also add nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates, but this may not be physiologically important. Probably plays a role in initiation of 16S rRNA degradation (leading to ribosome degradation) during starvation.
 
    0.990
guaA
GMP synthase domain protein; Catalyzes the synthesis of GMP from XMP.
 
 
 0.961
dut
Putative dUTP diphosphatase; This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA; Belongs to the dUTPase family.
  
 0.949
murI
Glutamate racemase; Provides the (R)-glutamate required for cell wall biosynthesis.
    0.933
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.
  
 0.928
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.
  
 0.927
purH
KEGG: tmt:Tmath_0637 1.1e-138 phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase K00602; Psort location: Cytoplasmic, score: 7.50.

hpt_1
KEGG: ccb:Clocel_2100 3.0e-49 hypoxanthine phosphoribosyltransferase K00760; Psort location: Cytoplasmic, score: 9.97; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.908
hpt_2
KEGG: tva:TVAG_243770 5.0e-63 hypoxanthine phosphoribosyltransferase; K00760 hypoxanthine phosphoribosyltransferase; Psort location: Cytoplasmic, score: 9.97; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.908
surE_3
5'/3'-nucleotidase SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
