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.

potFABC-type putrescine uptake system substrate-binding component PotF; Required for the activity of the bacterial periplasmic transport system of putrescine; Belongs to the bacterial solute-binding protein PotD/PotF family. (367 aa)    
Predicted Functional Partners:
potH
ABC-type putrescine uptake system permease component 1 PotH.
 
 0.999
potI
ABC-type putrescine uptake system permease component 2 PotI.
 0.999
potG
ABC-type putrescine uptake system ATPase component PotG; Part of the ABC transporter complex PotABCD involved in spermidine/putrescine import. Responsible for energy coupling to the transport system.
 0.997
puuP
Putrescine uptake protein PuuP.
      
 0.948
aguB
N-carbamoyl-putrescine amidase AguB.
  
  
 0.863
potE
Putrescine:ornithine antiporter 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. Belongs to the amino acid-polyamine-organocation (APC) superfamily. Basic amino acid/polyamine antiporter (APA) (TC 2.A.3.2) family.
      
 0.803
speD
S-adenosylmethionine decarboxylase SpeD.
      
 0.792
fbpC
ABC-type Fe3+ uptake system ATPase component FbpC; Belongs to the ABC transporter superfamily.
 
 
 0.733
speC
Ornithine decarboxylase SpeC; Belongs to the Orn/Lys/Arg decarboxylase class-II family.
      
 0.679
speE
Spermidine synthase SpeE; Catalyzes the irreversible transfer of a propylamine group from the amino donor S-adenosylmethioninamine (decarboxy-AdoMet) to putrescine (1,4-diaminobutane) to yield spermidine.
