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. (187 aa)    
Predicted Functional Partners:
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
 0.992
purH
purH: phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; [F] COG0138 AICAR transformylase/IMP cyclohydrolase PurH (only IMP cyclohydrolase domain in Aful).
 
 0.963
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.961
purB
purB: adenylosuccinate lyase; [F] COG0015 Adenylosuccinate lyase; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
  
 0.958
adk
Adenylate kinase family protein; Catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. Plays an important role in cellular energy homeostasis and in adenine nucleotide metabolism; Belongs to the adenylate kinase family.
  
 
 0.947
gpp
Phosphoribosyl transferase domain protein; Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily.
  
 
 0.939
gsk
pfkB carbohydrate kinase family protein; [G] COG0524 Sugar kinases, ribokinase family.
  
 0.936
hpt
HGPRTase: hypoxanthine phosphoribosyltransferase; [F] COG0634 Hypoxanthine-guanine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
   
 0.930
guaC
Guanosine monophosphate 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.
  
 
 0.928
surE
5'/3'-nucleotidase SurE; 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.
