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. (200 aa)    
Predicted Functional Partners:
guaA-2
GMP synthase (glutamine-hydrolyzing) domain protein; Catalyzes the synthesis of GMP from XMP.
  
 0.988
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.957
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; COG: COG0138; Pfam: PF02142,PF01808; InterPro: IPR002695.
 
 0.957
adk
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.
 
 
 0.951
purB
Adenylosuccinate lyase; COG: COG0015; Pfam: PF00206,PF08328; InterPro: IPR004769; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
  
 0.948
gpt
Xanthine phosphoribosyltransferase; Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily.
  
 
 0.935
gsk
Kinase, PfkB family; COG: COG0524; Pfam: PF00294; InterPro: IPR011611.
  
 0.931
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.
  
 
 0.926
hpt
Hypoxanthine phosphoribosyltransferase; COG: COG0634; Pfam: PF00156; InterPro: IPR005904; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
   
 0.926
