Hydrolase Superfamily
This superfamilly includes thioester hydrolases (Families 4.C.3 and 9.B.371) and proteases (8.A.51). These three families appear to be related although only distantly.
4.C.3 - The Acyl-CoA Thioesterase (ACoA-T) Family8.A.51 - The Dipeptidyl-aminopeptidase-like Protein 6 beta subunit of Kv4 channels (DPP6) Family
9.B.371 - The PaaI Thioesterase (PTE) Family
