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

prsARibose-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); Belongs to the ribose-phosphate pyrophosphokinase family. Class I subfamily. (313 aa)    
Predicted Functional Partners:
glmU
Bifunctional protein GlmU; Catalyzes the last two sequential reactions in the de novo biosynthetic pathway for UDP-N-acetylglucosamine (UDP-GlcNAc). The C- terminal domain catalyzes the transfer of acetyl group from acetyl coenzyme A to glucosamine-1-phosphate (GlcN-1-P) to produce N- acetylglucosamine-1-phosphate (GlcNAc-1-P), which is converted into UDP-GlcNAc by the transfer of uridine 5-monophosphate (from uridine 5- triphosphate), a reaction catalyzed by the N-terminal domain.

NIDE3114
Putative 2-oxoisovalerate dehydrogenase, beta subunit (Transketolase); Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
   
 0.953
pdhB
Pyruvate dehydrogenase E1 component, beta subunit (Transketolase); The pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO2.
   
 0.953
pdhB-2
Dehydrogenase (E1) component of pyruvate dehydrogenase complex, beta subunit (Transketolase); The pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO2.
   
 0.953
tktA
Transketolase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
   
 
 0.952
rplY
50S ribosomal protein L25; This is one of the proteins that binds to the 5S RNA in the ribosome where it forms part of the central protuberance. Belongs to the bacterial ribosomal protein bL25 family. CTC subfamily.
  
  
 0.937
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.
  
 0.935
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
  
 0.929
manB/pgm
Bifunctional Phosphoglucomutase/Phosphomannomutase; Function of strongly homologous gene; enzyme.
  
 0.926
rpiA
Ribose-5-phosphate isomerase A; Catalyzes the reversible conversion of ribose-5-phosphate to ribulose 5-phosphate.
  
 
 0.923
