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

caiCcrotonobetaine/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. (517 aa)    
Predicted Functional Partners:
caiA
Putative acyl-CoA dehydrogenase, carnitine metabolism; Catalyzes the reduction of crotonobetainyl-CoA to gamma- butyrobetainyl-CoA; Belongs to the acyl-CoA dehydrogenase family.
  
 0.984
caiD
Carnitine racemase; Catalyzes the reversible dehydration of L-carnitinyl-CoA to crotonobetainyl-CoA.
 0.976
entF
Enterobactin synthetase, component F (nonribosomal peptide synthetase); Similar to E. coli ATP-dependent serine activating enzyme (may be part of enterobactin synthase as component F) (AAC73687.1); Blastp hit to AAC73687.1 (1293 aa), 79% identity in aa 1 - 1293.
 
0.965
caiB
L-carnitine dehydratase; 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 (By similarity); Belongs to the CoA-transferase III family. CaiB subfamily.
 
  
 0.951
caiT
Putative BCCT family betaine/carnitine/choline transport protein; Catalyzes the exchange of L-carnitine for gamma-butyrobetaine and related betaines.
 
  
 0.894
STM0660
Putative cytoplasmic protein.
      
 0.891
fixC
Related to carnitine metabolism protein; Could be part of an electron transfer system required for anaerobic carnitine reduction; Belongs to the ETF-QO/FixC family.
 
  
 0.868
caiE
Stimulates carnitine racemase activity of CaiD and CaiB activity; Overproduction of CaiE stimulates the activity of CaiB and CaiD; Belongs to the transferase hexapeptide repeat family.
  
  
 0.853
fixA
Putative flavoprotein reductase, carnitine metabolism; Required for anaerobic carnitine reduction. May bring reductant to CaiA.
 
  
 0.808
fixB
Putative electron transfer flavoprotein, carnitine metabolism; Required for anaerobic carnitine reduction. May bring reductant to CaiA.
 
  
 0.808
