4-(trimethylamino)butanoyl-CoA + (R)-carnitine = (R)-carnitinyl-CoA + 4-(trimethylamino)butanoate
4-(trimethylamino)butanoyl-coa + (r)-carnitine = (r)-carnitinyl-coa + 4-(trimethylamino)butanoate
4-(trimethylamino)butanoyl-CoA + (R)-carnitine = (R)-carnitinyl-CoA + 4-(trimethylamino)butanoate
4-(trimethylamino)butanoyl-coa + (r)-carnitine = (r)-carnitinyl-coa + 4-(trimethylamino)butanoate
