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

spr1908Conserved hypothetical protein. (377 aa)    
Predicted Functional Partners:
pbp1b
Penicillin-binding protein 1b.
       0.795
tyrS
Tyrosyl-tRNA synthetase 1; Catalyzes the attachment of tyrosine to tRNA(Tyr) in a two- step reaction: tyrosine is first activated by ATP to form Tyr-AMP and then transferred to the acceptor end of tRNA(Tyr); Belongs to the class-I aminoacyl-tRNA synthetase family. TyrS type 1 subfamily.
       0.536
dapD
2,3,4,5-tetrahydropyridine-2-carboxylate N-succinyltransferase-related protein; Catalyzes the transfer of an acetyl group from acetyl-CoA to tetrahydrodipicolinate.
  
    0.512
mraY
Undecaprenyl-phosphate-UDP-MurNAc-pentapeptide phospho-MurNAc-pentapeptide transferase; First step of the lipid cycle reactions in the biosynthesis of the cell wall peptidoglycan; Belongs to the glycosyltransferase 4 family. MraY subfamily.
