The plasma propulsion with electronegative gases (PEGASES) thruster is a gridded ion thruster that accelerates alternately positively and negatively charged ions to provide thrust. Over the last few years, various prototypes have been tested, adequat

The Escherichia coli OmpF pore is governed by an internal constriction consisting of the negatively charged loop 3 folded into the lumen and the positively charged barrel wall located on the opposite side across the pore, ‘anti-loop 3'. To investig

Beta-lactam screening by specific residues of the OmpF eyelet

Autor: Jérôme Bredin, Jacques Barbe, Jean-Marie Pagès, Stéphanie Vidal

Publikováno v: Journal of medicinal chemistry. 48(5)

Beta-lactams use aqueous channels of porins to penetrate Gram-negative bacteria. The L3 loop of Escherichia coli OmpF porin is a key feature that actively contributes to both channel size and electrostatic properties. Acid residues D113, E117, and D1
