The permeation of most antibiotics through the outer membrane of Gram-negative bacteria occurs through porin channels. To design drugs with increased activity against Gram-negative bacteria in the face of the antibiotic resistance crisis, the strict

Gram-negative bacteria cause the majority of highly drug-resistant bacterial infections. To cross the outer membrane of the complex Gram-negative cell envelope, antibiotics permeate through porins, trimeric channel proteins that enable the exchange o

One-Step Purification and Porin Transport Activity of the Major Outer Membrane Proteins P2 from Haemophilus influenzae, FomA from Fusobacterium nucleatum and PorB from Neisseria meningitidis

Autor: Sabrina Pfennig, Paola Massari, Mikio Tanabe, Christof Kattner

Publikováno v: Applied Biochemistry and Biotechnology. 175:2907-2915

Bacterial porins are major outer membrane proteins that function as essential solute transporters between the bacteria and the extracellular environment. Structural features of porins are also recognized by eukaryotic cell receptors involved in innat

Among all Neisseriae species, Neisseria meningitidis and Neisseria gonorrhoeae are the only human pathogens, causative agents of bacterial meningitis and gonorrhoea, respectively. PorB, a pan-Neisseriae trimeric porin that mediates diffusive transpor

Identification of a cation transport pathway in Neisseria meningitidis PorB

Autor: Frank Jaenecke, Christof Kattner, Mikio Tanabe, Jan Zaucha, Ulrich Zachariae

Publikováno v: Proteins. 81(5)

Neisseria meningitidis is the main causative agent of bacterial meningitis. In its outer membrane, the trimeric Neisserial porin PorB is responsible for the diffusive transport of essential hydrophilic solutes across the bilayer. Previous molecular d
