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. (488 aa)    
Predicted Functional Partners:
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
 0.999
purH
KEGG: vpa:VP2896 phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; TIGRFAM: phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; PFAM: MGS domain protein; AICARFT/IMPCHase bienzyme, formylation region.
  
 0.994
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.
 
 
 0.989
purK
5-(carboxyamino)imidazole ribonucleotide synthase; Catalyzes the ATP-dependent conversion of 5-aminoimidazole ribonucleotide (AIR) and HCO(3)(-) to N5-carboxyaminoimidazole ribonucleotide (N5-CAIR); Belongs to the PurK/PurT family.
 
 
 0.954
Ping_3045
Non-canonical purine NTP pyrophosphatase, rdgB/HAM1 family 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.
 
 0.932
surE
5'-nucleotidase / 3'-nucleotidase; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.921
Ping_2695
PFAM: metallophosphoesterase; 5'-Nucleotidase domain protein; KEGG: sdn:Sden_2137 5'-nucleotidase; Belongs to the 5'-nucleotidase family.
   
 0.909
Ping_0151
TIGRFAM: HAD-superfamily hydrolase, subfamily IA, variant 3; PFAM: Haloacid dehalogenase domain protein hydrolase; KEGG: pat:Patl_0139 HAD-superfamily hydrolase, subfamily IA, variant 3.
    
 0.902
Ping_0156
PFAM: Haloacid dehalogenase domain protein hydrolase; KEGG: pfo:Pfl_0283 HAD-superfamily hydrolase subfamily IA, variant 3.
    
 0.902
purT
Formate-dependent phosphoribosylglycinamide formyltransferase; Involved in the de novo purine biosynthesis. Catalyzes the transfer of formate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR). Formate is provided by PurU via hydrolysis of 10-formyl-tetrahydrofolate; Belongs to the PurK/PurT family.
