Channel-forming (Porin) activity in Herpetosiphon aurantiacus Hp a2.

Rainer Harwardt1, Elke Maier, Hans Reichenbach, Jürgen Weckesser, Roland Benz.   

Abstract

Detergent extracts of cell envelopes of the gliding bacterium Herpetosiphon aurantiacus formed channels in lipid bilayers. Fast protein liquid chromatography across a HiTrap-Q cation-exchange column demonstrated that a 45-kDa protein forms the channel. The observation of a channel-forming protein suggests that Herpetosiphon aurantiacus Hp a2 has a permeability barrier on its surface.
