(a) NBSI is stacked between two adjacent base tiers, in which the omit composite map (contoured at level 1.0 σ) of NBSI is shown as well. (b) One water molecule W1 mediates the interaction of NBSI and two stacked residues A15 and G28. (c) The fully hydrated Mg2+, M1 forms interaction with the base of G28, the phosphate and the base of A27, the sugar and the phosphate of U8 through coordinated water molecules. N3 of C14 forms hydrogen-bonding interaction with 6-NH2 of A29.
