Structure of the Specificity Domain of Bacterial RNase P

Figure 1. Ribbon diagram of the Sdomain of B. subtilis RNase P. The P7P11 stems form a cruciform, with one helix in the cruciform formed by the stacking of P8 and P9, and the other by the stacking of P7, P10 and P11. The GAAA tetraloop at the end of P12 interacts with the tetraloop receptor in P10.1. The highly conserved J12/11J11/12 module forms a large structure devoid of Watson-Crick base pairs.
