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.

prsAPhosphoribosyltransferase:Purine/pyrimidine phosphoribosyl transferase; Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib- 5-P). (287 aa)    
Predicted Functional Partners:
MMP1332
NAD binding site:FAD-dependent pyridine nucleotide-disulphide oxidoreductase.
 
 0.970
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
  
 0.958
rpiA
Ribose 5-phosphate isomerase; Catalyzes the reversible conversion of ribose-5-phosphate to ribulose 5-phosphate.
 
 
 0.953
hisG
ATP phosphoribosyltransferase; Catalyzes the condensation of ATP and 5-phosphoribose 1- diphosphate to form N'-(5'-phosphoribosyl)-ATP (PR-ATP). Has a crucial role in the pathway because the rate of histidine biosynthesis seems to be controlled primarily by regulation of HisG enzymatic activity. Belongs to the ATP phosphoribosyltransferase family. Long subfamily.

MMP1115
Transketolase, N terminal half.
  
 
 0.925
MMP1113
Transketoloase, C terminal half.
  
 
  0.920
gap
Glyceraldehyde 3-phosphate dehydrogenase.
  
  
 0.907
pyrE
Orotate phosphoribosyltransferase; Catalyzes the transfer of a ribosyl phosphate group from 5- phosphoribose 1-diphosphate to orotate, leading to the formation of orotidine monophosphate (OMP).
  
 
 0.899
tpiA
Triosephosphate isomerase; Belongs to the triosephosphate isomerase family.
  
  
 0.894
mdh
Malate dehydrogenase, MDHII (NADP+-dependent); Catalyzes the reversible oxidation of malate to oxaloacetate.
 
 0.892
