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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

potDSpermidine/putrescine-binding periplasmic protein; Required for the activity of the bacterial periplasmic transport system of putrescine and spermidine. Polyamine binding protein (348 aa)    
Predicted Functional Partners:
potC
Spermidine/putrescine transport system permease protein PotC; Required for the activity of the bacterial periplasmic transport system of putrescine and spermidine
 
 0.999
potB
Spermidine/putrescine transport system permease protein PotB; Required for the activity of the bacterial periplasmic transport system of putrescine and spermidine
 
 0.999
potA
Spermidine/putrescine import ATP-binding protein PotA; Part of the ABC transporter complex PotABCD involved in spermidine/putrescine import. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. Spermidine/putrescine importer (TC 3.A.1.11.1) family
 0.999
potI
Putrescine transport system permease protein PotI; Required for the activity of the bacterial periplasmic transport system of putrescine
  
 0.980
potH
Putrescine transport system permease protein PotH; Required for the activity of the bacterial periplasmic transport system of putrescine
  
 0.952
ydcV
Inner membrane ABC transporter permease protein YdcV; Probably part of the binding-protein-dependent transport system YdcSTUV; probably responsible for the translocation of the substrate across the membrane
  
 0.859
potE
Putrescine transporter PotE; Catalyzes both the uptake and excretion of putrescine. The uptake of putrescine is dependent on the membrane potential and the excretion involves putrescine-ornithine antiporter activity
