These mimic the state of the ribozyme that is released after exon ligation, and were obtained using construct OiD1-5 crystallized in the presence of different metal ions: K + /Mg 2+ (4E8M, 3.50 ... 5; resolution), Rb + /Mg 2+ (4E8P, 3.28 Å resolution), Tl + /Mg 2+ (4E8Q, 2.84 Å resolution), Cs + /Mg 2+ (4E8R, 3.36 Å resolution), NH 4 + /Mg 2+ (4E8N, 2.96 Å resolution), Na + /Mg 2+ (4FAX, 3.10 Å resolution), and K + /Ba 2+ (4E8V, 3.99 Å resolution) [ 30 ].
