The activated region of the delta toxin is composed of three distinct structural domains: an N-terminal helical bundle domain (InterPro: IPR005639) involved in membrane insertion and pore formation; a beta-sheet central domain involved in receptor binding; and a C-terminal beta-sandwich domain (InterPro: IPR005638) that interacts with the N-terminal domain to form a channel.
He is known for his intense fights with the WHO advocating for usage of DDT. [3] [4] Contrary to the scientific mainstream he thought of it as an „excellent powder“. [5] He serves as an advisor to the Bill & Melinda Gates Foundation and is on the board of Africa Fighting Malaria (AFM). [3]
