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

caiTL-carnitine:gamma-butyrobetaine antiporter; Catalyzes the exchange of L-carnitine for gamma-butyrobetaine and related betaines (504 aa)    
Predicted Functional Partners:
caiA
Crotonobetaine reductase subunit ii, fad-binding; Catalyzes the reduction of crotonobetainyl-CoA to gamma- butyrobetainyl-CoA . The electron donor could be the FixA/FixB complex
 
   
 0.978
caiB
Gamma-butyrobetainyl-coa:carnitine coa transferase; Catalyzes the reversible transfer of the CoA moiety from gamma-butyrobetainyl-CoA to L-carnitine to generate L-carnitinyl-CoA and gamma-butyrobetaine. Is also able to catalyze the reversible transfer of the CoA moiety from gamma-butyrobetainyl-CoA or L- carnitinyl-CoA to crotonobetaine to generate crotonobetainyl-CoA
 
   
 0.973
caiC
Putative crotonobetaine/carnitine-coa ligase; Catalyzes the transfer of CoA to carnitine, generating the initial carnitinyl-CoA needed for the CaiB reaction cycle. Also has activity toward crotonobetaine and gamma-butyrobetaine
 
   
 0.962
caiD
Crotonobetainyl-coa hydratase; Catalyzes the reversible dehydration of L-carnitinyl-CoA to crotonobetainyl-CoA
 
   
 0.921
caiE
Stimulator of caid and caib enzyme activities; Overproduction of CaiE stimulates the activity of CaiB and CaiD
     
 0.910
caiF
Dna-binding transcriptional activator caif; Potential transcriptional activator of carnitine metabolism
  
   
 0.821
fixA
Anaerobic carnitine reduction putative electron transfer flavoprotein subunit; Required for anaerobic carnitine reduction. May bring reductant to CaiA
 
   
 0.738
yhjE
Putative transporter yhje; Inner membrane metabolite transport protein YhjE; Putative transport protein
      
 0.618
proP
Mfs transporter, mhs family, proline/betaine transporter; Proton symporter that senses osmotic shifts and responds by importing osmolytes such as proline, glycine betaine, stachydrine, pipecolic acid, ectoine and taurine. It is both an osmosensor and an osmoregulator which is available to participate early in the bacterial osmoregulatory response
      
 0.604
yehX
Glycine betaine abc transporter atp binding subunit yehx; Part of an ABC transporter complex involved in low-affinity glycine betaine uptake. Probably responsible for energy coupling to the transport system
     
 0.580
