Lysosomal thioesterase PPT2 (PPT-2), also known as S-thioesterase G14, is an enzyme that in humans is encoded by the PPT2 gene.^[5]^[6]^[7]

Function

This gene encodes a member of the palmitoyl protein thioesterase family. The encoded glycosylated lysosomal protein has palmitoyl-CoA hydrolase activity in vitro, but does not hydrolyze palmitate from cysteine residues in proteins.^[5]
