Summary of the enzymatic and chemical probing results for IFNA5 RNA (197–446). Mapping data are depicted upon common predicted secondary structure of different species using Centroid program http://www.ncrna.org/centroidfold/. Enzymatic cuts are showed as arrow heads (RNase T1), circles (RNase V1) and arrows (RNase A). The bases modified by DEPC are indicated by rhomboids and those cleaved by Pb²⁺ by stars. Strong cleavages are indicated by filled symbols and moderate ones by unfilled symbols. (+) and (−) enhanced or protected cleavage in MgCl₂. Numbers indicate nucleotide positions. D domain, l loop, PK possible pseudoknot. In blue, sequences participating in a predicted pseudoknot. Highlighted in gray are CAR-E sequences
