...uence. Nanoarchaeum equitans, is a member of a new phylogenetic kingdom in the Archaea containing organisms that are primitive, parasitic and extremophile, or notable for living in the most extreme environments.

He determined which protein family each toxin type belonged to, and based the normal expression pattern of that protein family, he predicted from which tissue type each toxin protein had been derived.
