Porins are proteins that are located in the outer membrane of Gram-negative bacteria. They function to form a water-filled pore through the membrane, from the exterior to the periplasm, which is a region located between the outer and inner membranes....

ABSTRACT OmpF from the outer membrane of Escherichia coli is a general porin considered to be the main pathway for [beta ]-lactam antibiotics. The availability of a high-resolution crystal structure of OmpF and new experimental techniques at the single-molecule level have opened the...

ABSTRACT Mitochondrial porins are predicted to traverse the outer membrane as a series of β-strands, but the precise structure of the resulting β-barrel has remained elusive. Toward determining the positions of the membrane-spanning segments, a series of small deletions was introduced into several...
