Etotal | Etwist | Ebend | |
---|---|---|---|
Linear DNA + GalR | |||
AL1 loop | 26.0 | 6.4 | 21.2 |
AL2 loop | 28.0 | 7.6 | 22.2 |
Linear DNA + GalR + HU bound to hbs (+6.5) | |||
AL1 loop | 9.4 | 8.7 | 5.8 |
AL2 loop | 25.5 | 14.9 | 13.6 |
Values for the loops formed by transient interaction of operator-bound GalR dimers were calculated as described in Materials and Methods. Energy values (kcal/mole) obtained in the presence of HU, bound at hbs (+6.5), are as described in Geanacopoulos et al. (2001).
