General annotation (Comments)

Function	Activates acetoacetate to acetoacetyl-CoA. May be involved in utilizing ketone body for the fatty acid-synthesis during adipose tissue development By similarity.
Catalytic activity	ATP + acetoacetate + CoA = AMP + diphosphate + acetoacetyl-CoA.
Subcellular location	Cytoplasm › cytosol By similarity.
Tissue specificity	Highly expressed in kidney, heart and brain, but low in liver. Ref.1
Sequence similarities	Belongs to the ATP-dependent AMP-binding enzyme family.
Sequence caution	The sequence AAH41000.1 differs from that shown. Reason: Frameshift at position 201. The sequence BAB14793.1 differs from that shown. Reason: Frameshift at position 519.
