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

pdxSPyridoxine biosynthesis glutamine amidotransferase, synthase subunit; Catalyzes the formation of pyridoxal 5'-phosphate from ribose 5-phosphate (RBP), glyceraldehyde 3-phosphate (G3P) and ammonia. The ammonia is provided by the PdxT subunit. Can also use ribulose 5- phosphate and dihydroxyacetone phosphate as substrates, resulting from enzyme-catalyzed isomerization of RBP and G3P, respectively. Belongs to the PdxS/SNZ family. (298 aa)    
Predicted Functional Partners:
pdxT
Pyridoxine biosynthesis glutamine amidotransferase, glutaminase subunit; Catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the biosynthesis of pyridoxal 5'-phosphate. The resulting ammonia molecule is channeled to the active site of PdxS.
 0.999
prs
Ribose-phosphate pyrophosphokinase; 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).
  
 
  0.809
rpiA
Ribose 5-phosphate isomerase A; Catalyzes the reversible conversion of ribose-5-phosphate to ribulose 5-phosphate.
    
  0.802
AKB66342.1
Phosphomannomutase; Belongs to the phosphohexose mutase family.
     
  0.800
guaAB
GMP synthase (glutamine-hydrolyzing), ATP pyrophosphatase subunit; Catalyzes the synthesis of GMP from XMP.
    
 0.763
guaAA
GMP synthase (glutamine-hydrolyzing), amidotransferase subunit; Catalyzes the synthesis of GMP from XMP.
    
 0.748
hisF
Imidazole glycerol 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.
    
 0.747
hisH
Imidazole glycerol phosphate synthase 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.
    
  0.740
AKB63535.1
Glutamine synthetase type I.
  
 
 0.736
gatA
Aspartyl-tRNA(Asn) amidotransferase subunit A / Glutamyl-tRNA(Gln) amidotransferase subunit A; Allows the formation of correctly charged Gln-tRNA(Gln) through the transamidation of misacylated Glu-tRNA(Gln) in organisms which lack glutaminyl-tRNA synthetase. The reaction takes place in the presence of glutamine and ATP through an activated gamma-phospho-Glu- tRNA(Gln).
