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. (182 aa)    
Predicted Functional Partners:
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
  
 0.996
guaB
Inosine-5'-monophosphate dehydrogenase; 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.

Contains possible transmembrane domain at N-terminus; Updated (2006) note: One probable transmembrane helix predicted by TMHMM2.0. Functional classification -Membranes, lipoproteins and porins.
  
  
 0.909
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
   
 
 0.850
ychF
Putative GTP-binding protein; ATPase that binds to both the 70S ribosome and the 50S ribosomal subunit in a nucleotide-independent manner.
  
 
  0.843
purB
Adenylosuccinate lyase; Original (2000) note: Cj0023, purB, probable adenylosuccinate lyase, len: 442 aa; similar to e.g. PUR8_BACSU adenylosuccinate lyase (EC 4.3.2.2) (431 aa),fasta scores; opt: 1369 z-score: 2264.2 E(): 0, 49.9% identity in 439 aa overlap. 67.9% identity to HP1112.

purN
Phosphoribosylglycinamide formyltransferase; Catalyzes the transfer of a formyl group from 10- formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate.
