CC -!- FUNCTION: Catalyzes the transfer of CoA to carnitine, generating the
CC initial carnitinyl-CoA needed for the CaiB reaction cycle. Also has
CC activity toward crotonobetaine and gamma-butyrobetaine.
CC {ECO:0000255|HAMAP-Rule:MF_01524}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=4-(trimethylamino)butanoate + ATP + CoA = AMP + diphosphate +
