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
TTE0620Xanthosine triphosphate pyrophosphatase; 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. (200 aa)    
Predicted Functional Partners:
Rph
RNase PH; 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.

GuaA
GMP synthase - PP-ATPase domain protein; Catalyzes the synthesis of GMP from XMP.

TTE0621
Predicted phosphoesterase; Best Blastp hit = gi|2501610|sp|Q58040|Y623_METJA HYPOTHETICAL PROTEIN MJ0623 gi|2128412|pir||G64377 hypothetical protein MJ0623 - Methanococcus jannaschii gi|1591334|gb|AAB98618.1| (U67510) conserved hypothetical protein [Methanococcus jannaschii], score 78.6, E-value 5.00E-14.
  
  
 0.971
GuaB
IMP dehydrogenase/GMP reductase; 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
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; Belongs to the NDK family.
  
 0.927
UshA
5-nucleotidase/2',3'-cyclic phosphodiesterase and related esterases; Best Blastp hit = gi|7481086|pir||T35760 probable nucleotidase - Streptomyces coelicolor gi|5689908|emb|CAB52071.1| (AL109732) putative nucleotidase [Streptomyces coelicolor A3(2)], score 325, E-value 3.00E-87.

Hpt
Best Blastp hit = gi|10172696|dbj|BAB03803.1| (AP001507) hypoxanthine-guanine phosphoribosyltransferase [Bacillus halodurans], score 189, E-value 2.00E-47; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.910
SurE
Survival protein, predicted acid phosphatase; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
