Lysosomal thioesterase PPT2 (PPT2)

Removes thioester-linked fatty acyl groups from various substrates such as S-palmitoyl-CoA. Has the highest S- thioesterase activity for the acyl groups palmitic and myristic acid followed by other short- and long-chain acyl substrates.

But because of structural constraints, is unable to eliminate palmitate from peptides or proteins. .
