Figure 6. The role of cis-interactions between N and Dl.

Figure 6

(A) Without cis-interactions the inhibitory delay (purple arrow) is long, including the time interval from N-Dl interaction to build-up of inhibitory E(spl); assuming cis-interaction, the delay is shortened to just N-Dl interaction and N cleavage. (B) Mechanism of cis-interaction between N and Dl. For detail, see text.
