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

aptAdenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis. (170 aa)    
Predicted Functional Partners:
guaA
GMP synthetase; Catalyzes the synthesis of GMP from XMP.
  
 0.993
adeC
Adenine deaminase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the metallo-dependent hydrolases superfamily. Adenine deaminase family.
 
 
 0.991
hprT
Hypoxanthine-guanine phosphoribosyltransferase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme.
  
 0.987
deoD
Purine nucleoside phosphorylase; Cleavage of adenosine and its derivatives; Belongs to the PNP/UDP phosphorylase family.
  
 
 0.977
guaC
GMP reductase; 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 (Probable).
  
 
 0.973
yerA
Putative adenine deaminase YerA; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
    
 0.970
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.968
pupG
Purine nucleoside phosphorylase; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate. Cleaves guanosine, inosine, 2'-deoxyguanosine and 2'-deoxyinosine.
  
 
 0.968
xpt
Xanthine phosphoribosyltransferase; Converts the preformed base xanthine, a product of nucleic acid breakdown, to xanthosine 5'-monophosphate (XMP), so that it can be reused for RNA or DNA synthesis; Belongs to the purine/pyrimidine phosphoribosyltransferase family. Xpt subfamily.
     
 0.967
purB
Adenylosuccinate lyase; Influences the affinity of glutamyl--tRNA ligase for its substrates and increases its thermostability; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
