Fig. 2.
Representative raw data of individual packaging events (filling vs. time) of WT, Y46F, and K84A terminases. Percentage of filling means percentage of the wild-type genome length (48,502 bp) packaged. Data are acquired using force feedback at a small constant load (≈5 pN) while packaging is taking place. Y46F* is a zoomed-in version of the graph depicting Y46F packaging events, where large (>100 bp) slips are marked with circles.
