palmitoyl-(protein) hydrolase activity

Definition

Target type: molecularfunction

Catalysis of the reaction: palmitoyl-protein + H2O = palmitate + protein. [EC:3.1.2.22]

Palmitoyl-(protein) hydrolase activity, also known as palmitoyl protein thioesterase activity, refers to the enzymatic hydrolysis of a thioester bond between a palmitoyl group and a protein. This specific type of hydrolase cleaves the fatty acid palmitate from the cysteine residue of a protein, removing a palmitoyl group. Palmitoylation is a reversible post-translational modification that involves the attachment of palmitate, a 16-carbon saturated fatty acid, to cysteine residues of proteins. This modification plays a crucial role in regulating protein localization, stability, and interaction with other proteins. Palmitoyl-(protein) hydrolase activity is essential for maintaining cellular homeostasis by controlling the level of palmitoylated proteins and influencing various cellular processes, including signal transduction, protein trafficking, and membrane organization.'
