Comments [?]

Function 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.
Catalytic activity RHEA:28526: (R)-carnitine + crotonobetainyl-CoA = (R)-carnitinyl-CoA + crotonobetaine
EC 2.8.3.21
RHEA:28418: (R)-carnitine + gamma-butyrobetainyl-CoA = (R)-carnitinyl-CoA + 4-(trimethylamino)butanoate
EC 2.8.3.21
Pathway Amine and polyamine metabolism; carnitine metabolism.
Subunit Homodimer.
Subcellular location Cytoplasm.
Similarity Belongs to the CoA-transferase III family. CaiB subfamily.
