Palmitoylated cysteine
WebTo test whether the only free cysteine residue of apoB-29, Cys-1085, was palmitoylated, we substituted a serine residue for this cysteine residue by site-directed mutagenesis. McArdle-RH7777 cell lines stably expressing similar levels of WT and Cys1085Ser mutant apoB-29s were then metabolically labeled with [ 125 I]iodopalmitate, as described in MATERIALS … Palmitoylation is the covalent attachment of fatty acids, such as palmitic acid, to cysteine (S-palmitoylation) and less frequently to serine and threonine (O-palmitoylation) residues of proteins, which are typically membrane proteins. The precise function of palmitoylation depends on the particular … See more S-palmitoylation is generally done by proteins with the DHHC domain. Exceptions exist in non-enzymatic reactions. Acyl-protein thioesterase (APT) catalyses the reverse reaction.
