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

prsAPhosphoribosylpyrophosphate synthetase; 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); Belongs to the ribose-phosphate pyrophosphokinase family. Class I subfamily. (315 aa)    
Predicted Functional Partners:
rbsK
Ribokinase; Catalyzes the phosphorylation of ribose at O-5 in a reaction requiring ATP and magnesium. The resulting D-ribose-5-phosphate can then be used either for sythesis of nucleotides, histidine, and tryptophan, or as a component of the pentose phosphate pathway.
   
 0.953
purF
Amidophosphoribosyltransferase = PRPP amidotransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine; In the C-terminal section; belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 0.951
tktB
Transketolase 2 isozyme; Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate.
  
 
 0.945
tktA
Transketolase 1 isozyme; Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate.
  
 
 0.945
rpiA
Ribosephosphate isomerase, constitutive; Catalyzes the reversible conversion of ribose-5-phosphate to ribulose 5-phosphate.
 
 
 0.933
deoB
Phosphopentomutase; Phosphotransfer between the C1 and C5 carbon atoms of pentose; Belongs to the phosphopentomutase family.
     
 0.914
pgm
Phosphoglucomutase; Residues 1 to 546 of 546 are 99.63 pct identical to residues 1 to 546 of 546 from Escherichia coli K-12 Strain MG1655: B0688.
     
 0.909
yqiE
Orf, hypothetical protein; Acts on ADP-mannose and ADP-glucose as well as ADP-ribose. Prevents glycogen biosynthesis. The reaction catalyzed by this enzyme is a limiting step of the gluconeogenic process (By similarity).
  
 
 0.906
yrfE
Orf, hypothetical protein; Residues 1 to 186 of 186 are 99.46 pct identical to residues 1 to 186 of 186 from Escherichia coli K-12 Strain MG1655: B3397.
  
 
 0.906
phnN
ATP-binding component of phosphonate transport; Catalyzes the phosphorylation of ribose 1,5-bisphosphate to 5-phospho-D-ribosyl alpha-1-diphosphate (PRPP).
     
  0.900
