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. (498 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.

PFAM: glutamine amidotransferase class-I; KEGG: bbt:BBta_0273 glutamine amidotransferase.
  
 
 0.979
purH
SMART: AICARFT/IMPCHase bienzyme formylation region; TIGRFAM: phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; KEGG: met:M446_2965 phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; PFAM: AICARFT/IMPCHase bienzyme formylation region; MGS domain protein.
  
 
 0.976
Rvan_1629
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.
  
 0.927
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine; In the C-terminal section; belongs to the purine/pyrimidine phosphoribosyltransferase family.
 
 
 0.923
pheT
KEGG: pla:Plav_0221 phenylalanyl-tRNA synthetase, beta subunit; TIGRFAM: phenylalanyl-tRNA synthetase, beta subunit.
  
  
 0.918
Rvan_0809
KEGG: mno:Mnod_7577 adenylosuccinate lyase; TIGRFAM: adenylosuccinate lyase; PFAM: fumarate lyase; Adenylosuccinate lyase-like; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
  
 
 0.908
rpoB
DNA-directed RNA polymerase, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
  
 0.876
purM
