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.

Score
RSc2160Putative xanthosine triphosphate pyrophosphatase protein; 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. (201 aa)    
Predicted Functional Partners:
rph
Probable ribonuclease ph (rnase ph) (trnanucleotidyltransferase) protein; 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.
 
    0.992
guaA
Probable gmp synthase [glutamine-hydrolyzing] (glutamineamidotransferase) (gmp synthetase) protein; Catalyzes the synthesis of GMP from XMP.
 
 
 0.973
dut
Deoxyuridine 5'-triphosphate nucleotidohydrolase (dutpase) (dutp pyrophosphatase) protein; 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.
  
 0.952
guaB
Probable inosine-5'-monophosphate dehydrogenase oxidoreductase protein; 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.
  
 0.949
purA
Probable adenylosuccinate synthetase (imp--aspartate ligase)(adss) (ampsase) protein; 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.
 
 0.948
ndk
Probable nucleoside diphosphate kinase (ndk) (ndp kinase)(nucleoside-2-p kinase) protein; 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.
 
 0.942
RSc2161
Heme chaperone HemW; Probably acts as a heme chaperone, transferring heme to an unknown acceptor. Binds one molecule of heme per monomer, possibly covalently. Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine. Belongs to the anaerobic coproporphyrinogen-III oxidase family.
    0.924
purH
Probable bifunctional purine biosynthesis purh [includes:phosphoribosylaminoimidazolecarboxamide formyltransferase (aicar transformylase); imp cyclohydrolase (inosinicase) (imp synthetase) (atic)]. transmembrane protein.
   
 
 0.920
murI
Probable glutamate racemase protein; Provides the (R)-glutamate required for cell wall biosynthesis.
 
    0.915
RSc0213
Putative glutamine amidotransferase protein.
  
 
 0.908
