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:
some 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

oppAOligopeptide abc transporter periplasmic binding protein; This protein is a component of the oligopeptide permease, a binding protein-dependent transport system, it binds peptides up to five amino acids long with high affinity (543 aa)    
Predicted Functional Partners:
oppB
Murein tripeptide abc transporter/oligopeptide abc transporter inner membrane subunit oppb; Part of the binding-protein-dependent transport system for oligopeptides; probably responsible for the translocation of the substrate across the membrane
 0.999
oppC
Murein tripeptide abc transporter/oligopeptide abc transporter inner membrane subunit oppc; Part of the binding-protein-dependent transport system for oligopeptides; probably responsible for the translocation of the substrate across the membrane
 0.999
oppD
Murein tripeptide abc transporter/oligopeptide abc transporter atp binding subunit oppd; Part of the binding-protein-dependent transport system for oligopeptides. Probably responsible for energy coupling to the transport system
 0.999
oppF
Murein tripeptide abc transporter/oligopeptide abc transporter atp binding subunit oppf; Part of the binding-protein-dependent transport system for oligopeptides. Probably responsible for energy coupling to the transport system
 0.998
mppA
Murein tripeptide (l-ala-gamma-d-glutamyl-meso-dap) transporter subunit; Essential for the uptake of the murein peptide L-alanyl- gamma-D-glutamyl-meso-diaminopimelate. Also transports some alpha- linked peptides such as Pro-Phe-Lys with low affinity. The transport is effected by the oligopeptide permease system
  
 
0.831
metQ
L-methionine/d-methionine abc transporter membrane anchored binding protein; This protein is a component of a D-methionine permease, a binding protein-dependent, ATP-driven transport system
   
 
 0.752
yejA
Putative oligopeptide abc transporter periplasmic binding protein; To H.influenzae HbpA
     
 0.736
malE
Maltose/maltodextrin transport system substrate-binding protein; Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Binds maltose and higher maltodextrins such as maltotriose
     
 0.734
dppA
Dipeptide/heme abc transporter periplasmic binding protein; Dipeptide-binding protein of a transport system that can be subject to osmotic shock. DppA is also required for peptide chemotaxis
  
0.703
gcvA
Lysr family transcriptional regulator, glycine cleavage system transcriptional activator; Regulatory protein for the glycine cleavage system operon (gcv). Mediates activation of gcv by glycine and repression by purines. GcvA is negatively autoregulated. Binds to three sites upstream of the gcv promoter
