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

proB
Prob protein; Catalyzes the transfer of a phosphate group to glutamate to form L-glutamate 5-phosphate.
 
 
 0.849
proA
ProA protein; Catalyzes the NADPH-dependent reduction of L-glutamate 5- phosphate into L-glutamate 5-semialdehyde and phosphate. The product spontaneously undergoes cyclization to form 1-pyrroline-5-carboxylate. Belongs to the gamma-glutamyl phosphate reductase family.

azo3467
Conserved hypothetical protein; Pyridoxal 5'-phosphate (PLP)-binding protein, which is involved in PLP homeostasis; Belongs to the pyridoxal phosphate-binding protein YggS/PROSC family.
 
  
 0.813
yggU
Conserved hypothetical protein. Homology to vc0458 of V. clholerae of 48% (sprot:Y458_VIBCH). InterPro: DUF167 (IPR003748). Pfam: Uncharacterized ACR, YGGU family, COF1872. no signal peptide. no TMHs; Belongs to the UPF0235 family.
     
 0.810
azo3076
Conserved hypothetical protein. Homology to TdenA01001814 of Thiobacillus denitrificans of 40% (gi|52006871|ref|ZP_00334250.1|(NBCI ENTREZ)). Has PF01402, Ribbon-helix-helix protein, copG family; IPR002145 HTH_CopG; The structure of this protein repressor, which is the shortest reported to date and the first isolated from a plasmid, has a homodimeric ribbon-helix-helix arrangement. The helix-turn-helix-like structure is involved in dimerisation and not DNA binding as might have been expected. No TMHs. No signal peptide.
