Figure 7.

Schematic representation of the three different types of tRNase Zs identified in green plants. The N-terminal half (eukaryotic-type-N) and C-terminal half (eukaryotic-type-C) of the eukaryotic-type tRNase ZL are shown separately. Motifs are indicated by colored boxes: red, specific to TM-type; green, specific to both bacterial- and eukaryotic-type; and blue, common to all three types. N and C denote N and C terminus, respectively. Relative positions of these motifs are not drawn to scale. The predicted functions of each motif are also indicated.
