Research Abstract |
Ribosomes in all organisms have a unique flexible structure composed of ribosomal protein complex, termed the stalk, which plays a crucial role in ribosome function. In this research subject, we have investigated the structure and function of the ribosomal stalk in a hyperthermophilic archaeon by biochemical and crystallographic analyses. The results showed that the archaeal stalk is composed of aP0 and aP1, which form the heptameric complex aP0(aP1)_2(aP1)_2(aP1)_2, and that the C-terminal sequence, which is shared by aP1 and aP0, directly binds to translation factors. We concluded that the 7 copies of C-terminal tails of aP1/aP0 in the complex participate in efficient recruitment of translation factors onto the ribosome.
