CC -!- FUNCTION: Catalyzes the reversible transfer of the CoA moiety from
CC gamma-butyrobetainyl-CoA to L-carnitine to generate L-carnitinyl-CoA
CC and gamma-butyrobetaine. Is also able to catalyze the reversible
CC transfer of the CoA moiety from gamma-butyrobetainyl-CoA or L-
CC carnitinyl-CoA to crotonobetaine to generate crotonobetainyl-CoA.
CC {ECO:0000255|HAMAP-Rule:MF_01050}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(R)-carnitine + crotonobetainyl-CoA = (R)-carnitinyl-CoA +
CC crotonobetaine; Xref=Rhea:RHEA:28526, ChEBI:CHEBI:16347,
CC ChEBI:CHEBI:17237, ChEBI:CHEBI:60932, ChEBI:CHEBI:60933; EC=2.8.3.21;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01050};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(R)-carnitine + gamma-butyrobetainyl-CoA = (R)-carnitinyl-CoA
CC + 4-(trimethylamino)butanoate; Xref=Rhea:RHEA:28418,
CC ChEBI:CHEBI:16244, ChEBI:CHEBI:16347, ChEBI:CHEBI:60932,
CC ChEBI:CHEBI:61513; EC=2.8.3.21; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01050};
CC -!- PATHWAY: Amine and polyamine metabolism; carnitine metabolism.
CC {ECO:0000255|HAMAP-Rule:MF_01050}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01050}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01050}.
CC -!- SIMILARITY: Belongs to the CoA-transferase III family. CaiB subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01050}.
