Figure 1

Schematic drawing of the consensus structures of RNase P RNA (adapted from [34, 46–48]). The table indicates the distribution of structural elements. Fungi type A conforms to the major eukaryotic distribution, while fungi type B structures have an additional P8' stem. A black circle in the table represents the occurrence of a particular element. Grey circles indicate features with extreme variations in some species. An ellipse indicates that two elements are merged and cannot be separated unambiguously.
