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.

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. (500 aa)    
Predicted Functional Partners:
guaAB
GMP synthase, glutamine-hydrolyzing, C-terminal domain or B subunit; Catalyzes the synthesis of GMP from XMP.
 
 0.994
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.
 
 
 0.987
guaAA
GMP synthase, glutamine-hydrolyzing, N-terminal domain or A subunit; Catalyzes the synthesis of GMP from XMP.
 
 
 0.977
AGB29973.1
GMP synthase family protein; PFAM: Glutamine amidotransferase class-I.
 
 
 0.971
AGB33001.1
AICAR transformylase/IMP cyclohydrolase PurH; PFAM: AICARFT/IMPCHase bienzyme; Formyl transferase; TIGRFAM: phosphoribosylglycinamide formyltransferase, formyltetrahydrofolate-dependent.
 
 
 0.966
AGB30604.1
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.
  
 0.935
surE-2
5'/3'-nucleotidase SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
 
  
 0.929
surE
5'/3'-nucleotidase SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
 
  
 0.928
purO
IMP cyclohydrolase; Catalyzes the cyclization of 5-formylamidoimidazole-4- carboxamide ribonucleotide to IMP.
 
  
 0.928
AGB30605.1
PFAM: IMP dehydrogenase / GMP reductase domain; TIGRFAM: guanosine monophosphate reductase, eukaryotic.
