a, Consensus sequence and secondary structure model of the riboswitch candidate class called the DUF1646 motif. The consensus model is based on the alignment of 308 nonredundant examples. b, Existing annotations of the protein products whose genes are associated with DUF1646 motif RNAs. c, Alkali (I) and alkaline earth (II) cations considered as candidate ligands for the putative aptamer formed by DUF1646 motif RNAs. Numbers represent the ionic radius (pm) in crystal form50 for the mono- or divalent forms of the elements indicated.
