Chains	Accession	Name	Description	Comments	Source
A, B	PF02551	Acyl-CoA thioesterase (Acyl_CoA_thio)	Acyl-CoA thioesterase	This family represents the thioesterase II domain. Two copies of this domain are found in a number of acyl-CoA thioesterases.	Domain
A, B	PF13622	Acyl-CoA thioesterase N-terminal domain (4HBT_3)	Acyl-CoA thioesterase N-terminal domain	This family contains a wide variety of enzymes, principally acyl-CoA thioesterases. These enzymes are part of the Hotdog fold superfamily [1]. This entry is usually found as the N-terminal part of a pair of HotDog domains.	Domain
