Figure 3. Scheme of the proposed two-step palmitoylation mechanism of PATs.

Figure 3

A covalent palmitoyl thioester enzyme intermediate is formed in the first auto-palmitoylation step, followed by the transfer of the palmitoyl moiety from PAT to the substrate protein in the second trans-palmitoylation step.
