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

caiBCrotonobetainyl 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. Belongs to the CoA-transferase III family. CaiB subfamily. (405 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.
 
 
 0.994
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. Belongs to the ATP-dependent AMP-binding enzyme family.
 
  
 0.987
caiD
carnitinyl-CoA dehydratase; Catalyzes the reversible dehydration of L-carnitinyl-CoA to crotonobetainyl-CoA.
 
 0.978
caiT
Putative transporter; Catalyzes the exchange of L-carnitine for gamma-butyrobetaine and related betaines.
 
  
 0.962
caiE
Stimulator of CaiD and CaiB enzyme activities; Overproduction of CaiE stimulates the activity of CaiB and CaiD; Belongs to the transferase hexapeptide repeat family.
     
 0.922
fixB
Protein FixB; Required for anaerobic carnitine reduction. May bring reductant to CaiA; Belongs to the ETF alpha-subunit/FixB family.
 
  
 0.849
fixA
Anaerobic carnitine reduction putative electron transfer flavoprotein subunit; Required for anaerobic carnitine reduction. May bring reductant to CaiA; Belongs to the ETF beta-subunit/FixA family.
 
 
 0.804
ydiO
Putative acyl-CoA dehydrogenase; Putative oxidoreductase; Belongs to the acyl-CoA dehydrogenase family.
 
 
 0.761
fixC
