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

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. (486 aa)    
Predicted Functional Partners:
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
 0.999
purA
Adenylosuccinate synthetase; 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.
 
 
 0.992
AFM25525.1
GMP synthase family protein; PFAM: Glutamine amidotransferase class-I.
 
 
 0.968
AFM27633.1
AICAR transformylase/IMP cyclohydrolase PurH; PFAM: AICARFT/IMPCHase bienzyme.
 
 
 0.966
AFM25444.1
GMP synthase family protein; PFAM: Glutamine amidotransferase class-I.
  
 
 0.963
AFM25528.1
PFAM: Phosphoribosyl transferase domain; TIGRFAM: hypoxanthine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
    
 0.938
surE
5'-nucleotidase, exopolyphosphatase, 3'-nucleotidase; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.938
AFM26415.1
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.
  
 0.938
AFM26414.1
5'-nucleotidase/2',3'-cyclic phosphodiesterase-like hydrolase; PFAM: Calcineurin-like phosphoesterase; 5'-nucleotidase, C-terminal domain; Belongs to the 5'-nucleotidase family.
    
 0.922
pheT
phenylalanyl-tRNA synthetase, beta subunit; PFAM: tRNA synthetase B5 domain; B3/4 domain; Ferredoxin-fold anticodon binding domain; Putative tRNA binding domain; TIGRFAM: phenylalanyl-tRNA synthetase, beta subunit, non-spirochete bacterial; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
