FIGURE 4.
Summary of protein-protein interactions detected in archaeal systems. Data from previously published yeast two-hybrid studies are summarized. Tables are drawn such that homologous proteins are represented in similar positions in both tables, starting from the top left corner. The interactions are indicated as described in the original text. (A). Interactions demonstrated in protein components of the Pyrococcus horikoshii OT3 RNase P (Kifusa et al., 2005). (B). Interactions demonstrated in protein components of the Methanothermobacter thermoautotrophicus RNase P (Hall and Brown, 2004).
