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

Score
avtAValine-pyruvate aminotransferase; Involved in the biosynthesis of alanine. Belongs to the class-I pyridoxal-phosphate-dependent aminotransferase family. (417 aa)    
Predicted Functional Partners:
ilvE
Branched-chain amino acid aminotransferase; Acts on leucine, isoleucine and valine.
     
 0.989
alaA
Glutamate-pyruvate aminotransferase; Involved in the biosynthesis of alanine.
   
 
 0.981
leuA
2-isopropylmalate synthase; Catalyzes the condensation of the acetyl group of acetyl-CoA with 3-methyl-2-oxobutanoate (2-oxoisovalerate) to form 3-carboxy-3- hydroxy-4-methylpentanoate (2-isopropylmalate); Belongs to the alpha-IPM synthase/homocitrate synthase family. LeuA type 1 subfamily.
   
 
 0.958
ilvD
Dihydroxyacid dehydratase.
     
 0.952
malS
Alpha-amylase; Since only maltooligosaccharides up to a chain length of 6 glucose units are actively transported through the cytoplasmic membrane via the membrane-bound complex of three proteins, MalF, MalG, and MalK, longer maltooligosaccharides must first be degraded by the periplasmic alpha-amylase, the MalS protein; Belongs to the glycosyl hydrolase 13 family.
    
 0.847
alaC
Glutamate-pyruvate aminotransferase; Involved in the biosynthesis of alanine.
      
 0.808
tyrB
Tyrosine aminotransferase, tyrosine-repressible, PLP-dependent; Broad-specificity enzyme that catalyzes the transamination of 2-ketoisocaproate, p-hydroxyphenylpyruvate, and phenylpyruvate to yield leucine, tyrosine, and phenylalanine, respectively. In vitro, is able to catalyze the conversion of beta-methyl phenylpyruvate to the nonproteinogenic amino acid (2S,3S)-beta-methyl-phenylalanine, a building block of the antibiotic mannopeptimycin produced by Streptomyces hygroscopicus NRRL3085; Belongs to the class-I pyridoxal-phosphate-dependent aminotransferase family.
   
  
 0.788
xylR
Xylose divergent operon transcriptional activator; Regulatory protein for the xylBAFGHR operon.
 
      0.677
ilvC
Ketol-acid reductoisomerase, NAD(P)-binding; 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. Also able to use 2-ketopantoate, 2-ketoisovalerate, 2-ketovalerate, 2-ketobutyrate [...]
   
  
 0.673
aspC
Aspartate aminotransferase, PLP-dependent; Aspartate aminotransferase; Protein involved in cellular amino acid catabolic process and aspartate biosynthetic process.
  
  
 0.670
