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

ppdPhosphonopyruvate decarboxylase; Function of strongly homologous gene; enzyme. (375 aa)    
Predicted Functional Partners:
NIDE2903
Putative Phosphoenolpyruvate phosphomutase (modular protein); Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
 0.992
ilvH
Acetolactate synthase, small subunit; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
 
 0.954
phnW
2-aminoethylphosphonate aminotransferase; Function of strongly homologous gene; enzyme.
 
 
 0.942
ilvC
Ketol-acid reductoisomerase; Involved in the biosynthesis of branched-chain amino acids (BCAA). Catalyzes an alkyl-migration followed by a ketol-acid reduction of (S)-2-acetolactate (S2AL) to yield (R)-2,3-dihydroxy-isovalerate. In the isomerase reaction, S2AL is rearranged via a Mg-dependent methyl migration to produce 3-hydroxy-3-methyl-2-ketobutyrate (HMKB). In the reductase reaction, this 2-ketoacid undergoes a metal-dependent reduction by NADPH to yield (R)-2,3-dihydroxy-isovalerate.

NIDE3330
Conserved protein of unknown function, SDR family; Homologs of previously reported genes of unknown function; 7742302.
  
 0.720
ilvD
Dihydroxy-acid dehydratase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the IlvD/Edd family.
  
  
 0.674
gltB
Glutamate synthase, alpha subunit; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
  
 0.577
leuD
3-isopropylmalate dehydratase, small subunit; Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate. Belongs to the LeuD family. LeuD type 1 subfamily.
  
  
 0.528
prpB
2-methylisocitrate lyase; Catalyzes the thermodynamically favored C-C bond cleavage of (2R,3S)-2-methylisocitrate to yield pyruvate and succinate.
  
 0.494
