Figure 1.
Figure 1. A, Crystal structure of EcoRV bound to the specific DNA undecamer 5′-AAAGATATCTT [Kostrewa and Winkler 1995]. B, Crystal structure of EcoRV bound to two non-specific DNA octamers CGAGCTCG [Winkler et al 1993], in which the two octamers are stacked end-to-end with phosphates in the scissile position missing. C, Crystal structure of EcoRV complexed with the two duplexes d(AAAGAT) + d(ATCTT), also with the scissile phosphates missing (Table 1). The helical axes of the DNA are indicated by the continuous black lines in each case.
