Chains	Enzyme Name	Description	Catalytic Residues
A	palmitoyl[protein] hydrolase (type 2) M-CSA #523	Palmitoyl protein thioesterase 2 (PPT2) is a lysosomal enzyme with thioesterase activity. It will remove palmitate from palmitoyl CoA but is unable to remove palmitate groups from several S-palmitoylated proteins; in this respect it differs from the closely related enzyme PPT1.
