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

guaCHypothetical protein; Catalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides. (347 aa)    
Predicted Functional Partners:
guaA
Hypothetical protein; Catalyzes the synthesis of GMP from XMP.
 
 0.997
purA
Hypothetical protein; 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.
  
 
 0.986
CKO_00370
Hypothetical protein; KEGG: noc:Noc_2237 2.9e-31 glutamine amidotransferase class-I K01951; COG: COG0518 GMP synthase - Glutamine amidotransferase domain.
  
 
 0.971
purH
Hypothetical protein; KEGG: spt:SPA4013 4.4e-273 purH; phosphoribosylaminoimidazolecarboxamide formyltransferase and IMP cyclohydrolase (bifunctional enzyme) K00602:K01492; COG: COG0138 AICAR transformylase/IMP cyclohydrolase PurH (only IMP cyclohydrolase domain in Aful).
  
 
 0.959
apt
Hypothetical protein; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.932
gpt
Hypothetical protein; Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily.
  
 
 0.931
surE
Hypothetical protein; Nucleotidase with a broad substrate specificity as it can dephosphorylate various ribo- and deoxyribonucleoside 5'-monophosphates and ribonucleoside 3'-monophosphates with highest affinity to 3'-AMP. Also hydrolyzes polyphosphate (exopolyphosphatase activity) with the preference for short-chain-length substrates (P20-25). Might be involved in the regulation of dNTP and NTP pools, and in the turnover of 3'-mononucleotides produced by numerous intracellular RNases (T1, T2, and F) during the degradation of various RNAs.
    
 0.929
gmk
Hypothetical protein; Essential for recycling GMP and indirectly, cGMP.
    
 0.929
CKO_03242
Hypothetical protein; KEGG: sfx:S0124 3.9e-91 hpt; hypoxanthine phosphoribosyltransferase K00760; COG: COG0634 Hypoxanthine-guanine phosphoribosyltransferase; Psort location: Cytoplasmic, score:9.97; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
    
 0.924
guaB
Hypothetical protein; 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.
