(a) Interaction between the A patch on helix 2 (in yellow stick) with the minor groove of helix 26 (shown in surface representation). A519, A520, and A521 of helix 2 make type III, type II, and type I interactions, respectively, typical of A-patch packing geometry in the A-minor motif. (b) 5S rRNA solely interacts with 23S rRNA via a symmetric A-patch interaction between three stacked adenosines of the 5S rRNA loop E helix and three stacked adenosines in helix 38 of 23S rRNA.
