Figure 4. Chemical methods to enrich lipidated proteins.
(A, B) Treatment of cells with alkyne myristic acid (Alk-12) or alkyne palmitic acid (Alk-16) results in labeling of N-myristoylated proteins or S-palmitoylated proteins, respectively. (C) Acyl-biotin exchange: S-palmitoylated proteins can be tagged post-lysis by using a combination of thiol- and thioester-selective reactions. (D) Treatment of cells with alkyne farnesol results in labeling of S-prenylated proteins.
