Outline of Final Research Achievements

The aim of this study is to clarify the role of pyrite in serving as a major catalyst of prebiotic synthesis. Firstly, we performed proteomic analysis of pyrite-bearing sclerite of the scaly-foot gastropod and identified a small protein molecule that chelates Fe(III). By using a chemically analogous protein commercially available, we succeed in the synthesis of nano crystalline pyrite, suggesting that pyrite is in turn controlling the prebiotic synthesis. We also performed metagenomic analysis of subsurface microbes in terrestrial granitic rocks and found primitive life forms closely related the last universal common ancestor. Together, we discovered biochemical processes and life forms potentially important for the study of the emergence of life on Earth.
