A novel hopanoid, 30-(5'-adenosyl)hopane, from the purple non-sulphur bacterium Rhodopseudomonas acidophila, with possible DNA interactions.

A novel hopanoid, 30-(5'-adenosyl)hopane, was isolated from the purple non-sulphur bacterium Rhodopseudomonas acidophila and identified. The significance of this triterpenoid in terms of bacteriohopanepolyol biosynthesis, membrane reinforcement and possible interactions with nucleic acids is discussed.
