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
guaBInosine-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. (487 aa)    
Predicted Functional Partners:
guaA
GMP synthase domain protein; Catalyzes the synthesis of GMP from XMP.
 0.999
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.
  
 
 0.986
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.
  
 
 0.984
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; KEGG: hhd:HBHAL_1598 5.6e-151 purH; bifunctional phosphoribosylaminoimidazolecarboxamide formyltransferase.
  
 
 0.982
Hpt
KEGG: sgo:SGO_2134 4.8e-58 hpt; hypoxanthine phosphoribosyltransferase K00760; Psort location: Cytoplasmic, score: 9.97; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
    
 0.961
KXB57638.1
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.
  
 0.954
Tkt
Transketolase; KEGG: ssa:SSA_2075 2.4e-260 tkt; transketolase K00615; Psort location: Cytoplasmic, score: 7.50; Belongs to the transketolase family.
  
 
 0.945
pheT
KEGG: sha:SH1822 4.3e-199 pheT; phenylalanyl-tRNA synthetase subunit beta; K01890 phenylalanyl-tRNA synthetase beta chain; Psort location: Cytoplasmic, score: 9.97.
  
  
 0.918
PurL
KEGG: ipo:Ilyop_2204 0. phosphoribosylformylglycinamidine synthase K01952; Psort location: Cytoplasmic, score: 9.97.
  
  
 0.885
ribA
3,4-dihydroxy-2-butanone-4-phosphate synthase; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; Belongs to the GTP cyclohydrolase II family. In the N-terminal section; belongs to the DHBP synthase family.
