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

cadBPutative lysine/cadaverine transporter; Probable cadaverine/lysine antiporter or part of it. (444 aa)    
Predicted Functional Partners:
cadA
Lysine decarboxylase, acid-inducible; Inducible lysine decarboxylase that catalyzes the proton- dependent decarboxylation of L-lysine to produce the polyamine cadaverine and carbon dioxide. Plays a role in pH homeostasis by consuming protons and neutralizing the acidic by- products of carbohydrate fermentation. Belongs to the Orn/Lys/Arg decarboxylase class-I family.
 
  
 0.998
cadC
cadBA operon transcriptional activator; Required for Pcad induction, a promoter upstream of cadBA that is responsible for the pH-regulated expression of CadA and CadB. Probably acts as an activating transcription factor.
 
  
 0.979
speF
Ornithine decarboxylase isozyme, inducible; Protein involved in polyamine biosynthetic process; Belongs to the Orn/Lys/Arg decarboxylase class-I family.
 
  
 0.899
ldcC
Lysine decarboxylase 2, constitutive; Plays a role in lysine utilization by acting as a lysine decarboxylase.
 
  
 0.897
gadA
Glutamate decarboxylase A, PLP-dependent; Converts glutamate to gamma-aminobutyrate (GABA), consuming one intracellular proton in the reaction. The gad system helps to maintain a near-neutral intracellular pH when cells are exposed to extremely acidic conditions. The ability to survive transit through the acidic conditions of the stomach is essential for successful colonization of the mammalian host by commensal and pathogenic bacteria.
     
 0.738
puuP
Putrescine importer; Involved in the uptake of putrescine. Belongs to the amino acid-polyamine-organocation (APC) superfamily.
  
   
 0.676
adiA
Arginine decarboxylase; ADC can be found in two forms: biodegradative and biosynthetic. The biodegradative form may play a role in regulating pH by consuming proteins; Belongs to the Orn/Lys/Arg decarboxylase class-I family.
 
  
 0.669
gadB
Glutamate decarboxylase B, PLP-dependent; Converts glutamate to gamma-aminobutyrate (GABA), consuming one intracellular proton in the reaction. The gad system helps to maintain a near-neutral intracellular pH when cells are exposed to extremely acidic conditions. The ability to survive transit through the acidic conditions of the stomach is essential for successful colonization of the mammalian host by commensal and pathogenic bacteria; Belongs to the group II decarboxylase family.
     
 0.656
lysP
Lysine transporter; Permease that is involved in the transport across the cytoplasmic membrane of lysine; Belongs to the amino acid-polyamine-organocation (APC) superfamily. Amino acid transporter (AAT) (TC 2.A.3.1) family.
      
 0.644
yaeR
Putative lyase; To B.subtilis YwkD.
      
 0.642
