Chains	Enzyme Name	Description	Catalytic Residues
A	palmitoyl[protein] hydrolase (type 1) M-CSA #522	Palmitoyl-protein thioesterase I (PPT1) is a lysosomal enzyme which is implicated in the degredation of lipid modified proteins, removing fatty acid groups from cysteine residues. The accumulation of undisgested substrate when a mutant enzyme is present leads to the formation of neuronal storage bodies that are associated with the clinical symptoms of infantile ceroid lipofuscinosis.
