PafA pupylation of titin-I27 variants. A, pupylation of titin-I27 variants (15 μm each) by PafA (0.5 μm) and Fl-PupE (1 μm). The inset demonstrates an I271 pupylation reaction with PafA (0.5 μm) and Fl-PupE (7 μm) that continued to completion. B, steady-state pupylation rates by PafA (0.5 μm) and Fl-PupE (15 μm) at increasing concentrations of titin-I27 variants. The curves are fitted to the Hill equation. The averages ± S.D. (error bars) of three experiments are presented.
