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

guaBIMP 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. (486 aa)    
Predicted Functional Partners:
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
 
 0.999
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.
 
 
 0.995
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; Bifunctional purine biosynthesis protein purH [Includes: Phosphoribosylaminoimidazolecarboxamide formyltransferase (EC 2.1.2.3) (AICAR transformylase); IMP cyclohydrolase (EC 3.5.4.10) (Inosinicase) (IMP synthetase) (ATIC)] InterPro: AICARFT/IMPCHase bienzyme; High confidence in function and specificity.
 
 
 0.993
surE
Phosphoric-monoester phosphohydrolase; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
   
 0.984
azo2531
Conserved hypothetical protein.
  
 
 0.978
azo3964
Conserved Hypothetical 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.
 
 0.967
ribAB
GTP cyclohydrolase II; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; Belongs to the DHBP synthase family.
  
 
 0.963
azo0794
Arabinose 5-phosphate isomerase (EC 5.3.1.13). Catalyzes the interconversion of D-arabinose 5-phosphate and D-ribulose 5-phosphate (By similarity). InterPro: KpsF/GutQ family protein kpsF: KpsF/GutQ family protein; High confidence in function and specificity; Belongs to the SIS family. GutQ/KpsF subfamily.
    
 0.959
hpt
Hypoxanthine phosphoribosyltransferase (Hypoxanthine-guanine phosphoribosyltransferase. (HGPRTase) (IMP pyrophosphorylase) (IMP diphosphorylase) (Transphosphoribosidase) (Guanine phosphoribosyltransferase); Function unclear.
    
 0.943
pyrD
Dihydroorotate oxidase; Catalyzes the conversion of dihydroorotate to orotate with quinone as electron acceptor; Belongs to the dihydroorotate dehydrogenase family. Type 2 subfamily.
