To establish a strategy to generate N-acylated proteins modified with fatty acids having a specific chain length, tGelsolin-streptag, an epitope-tagged model protein having an N-myristoylation motif, was synthesized using an insect cell-free protein synthesis system in the presence of acyl-CoA with various fatty acid chain lengths. It was found that the fatty acid species attached to the N-termini fully depended on the acyl-CoA species added to the reaction mixture. N-Acylated proteins with fatty acid chain lengths of 8, 10, 12, and 14 were generated successfully.
