- 論文の詳細を見る
SecA is an ATP-driven motor for protein translocation in bacteria and plants. Mycobacteria and listeria were recently found to possess two functionally distinct secA genes. In this study, we found that Cyanidioschyzon merolae, a unicellular red alga, possessed two distinct secA-homologous genes; one encoded in the cell nucleus and the other in the plastid genome. We found that the plastid-encoded SecA homolog showed significant ATPase activity at low temperature, and that the ATPase activity of the nuclear-encoded SecA homolog showed significant activity at high temperature. We propose that the two SecA homologs play different roles in protein translocation.
