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. (487 aa)    
Predicted Functional Partners:
guaA
GMP synthase, large subunit; 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.

Phosphoribosylaminoimidazolecarboxamideformyltra nsferase; COGs: COG0138 AICAR transformylase/IMP cyclohydrolase PurH (only IMP cyclohydrolase domain in Aful); InterPro IPR011607:IPR013982; KEGG: glo:Glov_2760 phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; PFAM: MGS domain protein; AICARFT/IMPCHase bienzyme formylation region; PRIAM: Phosphoribosylaminoimidazolecarboxamide formyltransferase; SPTR: B3E7F6 Bifunctional purine biosynthesis protein purH; PFAM: AICARFT/IMPCHase bienzyme; MGS-like domain.
  
 
 0.957
Deba_0490
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.
  
 0.936
surE
Stationary-phase survival protein SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.928
Deba_1086
COGs: COG0634 Hypoxanthine-guanine phosphoribosyltransferase; InterPro IPR000836:IPR005904; KEGG: sfu:Sfum_1422 hypoxanthine phosphoribosyltransferase; PFAM: phosphoribosyltransferase; PRIAM: Hypoxanthine phosphoribosyltransferase; SPTR: A0LI61 Hypoxanthine phosphoribosyltransferase; TIGRFAM: hypoxanthine phosphoribosyltransferase; PFAM: Phosphoribosyl transferase domain; TIGRFAM: hypoxanthine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
    
 0.928
purE
Phosphoribosylamine/glycine ligase; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR); Belongs to the GARS family.

ribBA
GTP cyclohydrolase II; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; In the C-terminal section; belongs to the GTP cyclohydrolase II family.
  
  
 0.867
purL
Phosphoribosylformylglycinamidine synthase; Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is thought to assist in [...]
