The genomic DNA of the B E strain of Escherichia coli has been scrutinized to detect porin genes that have not been identified so far. Southern blot analysis yielded two DNA segments which proved highly homologous to, yet distinct from, the ompC , om

Combination of an origin repair mutagenesis system with a new mutS host strain increased the efficiency of mutagenesis from 46% to 75% mutant clones. Overexpression with the T7 expression system afforded large quantities of proteins from mutant strai

OmpF porin is a nonspecific pore protein from the outer membrane of Escherichia coli. Previously, a set of mutants was selected that allow the passage of long maltodextrins that do not translocate through the wild-type pore. Here, we describe the cry

In the homotrimeric OmpF porin from Escherichia coli , each channel is constricted by a loop protruding into the β-barrel of the monomer about halfway through the membrane. The water-filled channels exist in open or closed states, depending on the t

The porins PhoE and OmpF form anion and cation-selective pores, respectively, in the outer membrane of Escherichia coli. Each monomer of these trimeric proteins consists of a 16-stranded beta-barrel, which contains a constriction at half the height o

The sole histidine residue in OmpF porin was replaced by threonine using site-directed mutagenesis. This exchange affected neither channel properties nor channel structure, as determined by X-ray analysis to 3.2 A. Conductance and critical voltage (V
