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. (172 aa)    
Predicted Functional Partners:
guaA
GMP synthase, large subunit; Catalyzes the synthesis of GMP from XMP.
  
 0.998
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.955
Pnec_1511
KEGG: pnu:Pnuc_1794 adenylosuccinate lyase; TIGRFAM: adenylosuccinate lyase; PFAM: fumarate lyase; Adenylosuccinate lyase domain protein; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
  
 0.954
purH
KEGG: pnu:Pnuc_1877 bifunctional phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; TIGRFAM: phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; PFAM: MGS domain protein; AICARFT/IMPCHase bienzyme formylation region.
  
 0.952
Pnec_0225
PFAM: PfkB domain protein; KEGG: pnu:Pnuc_0207 PfkB domain protein.
   
 0.950
adk
Nucleoside-triphosphate--adenylate kinase; 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.
  
 
 0.935
Pnec_1606
5'-nucleotidase; PFAM: 5-nucleotidase; KEGG: pnu:Pnuc_1901 5-nucleotidase.
     
  0.900
purL
Phosphoribosylformylglycinamidine synthase; Phosphoribosylformylglycinamidine synthase involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate.
  
  
 0.856
hisF
Imidazoleglycerol phosphate synthase, cyclase subunit; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit.
   
 
 0.819
hisH
Imidazole glycerol phosphate synthase, glutamine amidotransferase subunit; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisH subunit catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the synthesis of IGP and AICAR. The resulting ammonia molecule is channeled to the active site of HisF.
