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

oppDMurein 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 (337 aa)    
Predicted Functional Partners:
oppA
Oligopeptide 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
 0.999
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
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
 
0.997
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
 
 0.973
dppC
Dipeptide abc transporter membrane subunit dppc; Part of the binding-protein-dependent transport system for dipeptides; probably responsible for the translocation of the substrate across the membrane
 
 0.915

 0.789
nikC
Ni(2(+)) ABC transporter membrane subunit NikC; Involved in a nickel transport system, probably translocates nickel through the bacterial inner membrane
 
 
 0.789
ddpC
Putative d,d-dipeptide abc transporter membrane subunit ddpc; Part of the ABC transporter complex DdpABCDF, which is probably involved in D,D-dipeptide transport. Probably responsible for the translocation of the substrate across the membrane
 
 
 0.788
dppB
Dipeptide abc transporter membrane subunit dppb; Part of the binding-protein-dependent transport system for dipeptides; probably responsible for the translocation of the substrate across the membrane
