Lipid attachment through sortase-catalyzed transpeptidation. (a) Optimized procedure for lipid coupling followed by removal of His6-tagged proteins with Ni-NTA resin. (b) SDS-PAGE analysis of lipid-modified eGFP following transpeptidation and depletion of His6-tagged proteins. [Input = eGFP-LPETG-His6 in the absence of sortase and nucleophile, *Samples incubated with Ni-NTA resin and 300 mM imidazole to block binding of His6-tagged proteins].
