  • Acyl protein thioesterases are critical regulators of S-acylation, removing acyl chains from dynamically S-acylated proteins. A cytosolic deacylase, APT2, is S-acylated by zDHHC3 and zDHHC7 and is predicted to deform the lipid bilayer to extract acyl chains, capturing them within a hydrophobic pocket.
