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

SDX53241.1Usg protein (tryptophan operon, function unknown). (89 aa)    
Predicted Functional Partners:
gyrA
DNA gyrase subunit A; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner.
       0.659
dapA
4-hydroxy-tetrahydrodipicolinate synthase; Catalyzes the condensation of (S)-aspartate-beta-semialdehyde [(S)-ASA] and pyruvate to 4-hydroxy-tetrahydrodipicolinate (HTPA).
     
  0.499
SDW50175.1
Homoserine dehydrogenase.
     
  0.499
SDW54550.1
Diaminobutyrate aminotransferase apoenzyme; Catalyzes reversively the conversion of L-aspartate beta- semialdehyde (ASA) to L-2,4-diaminobutyrate (DABA) by transamination with L-glutamate; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.
     
  0.499
SDW54634.1
Aspartate kinase.
     
  0.499
SDW79713.1
Aspartate kinase; Belongs to the aspartokinase family.
     
  0.499
SDX53322.1
Hypothetical protein.
       0.498
