  title={Nonspecific porins of the outer membrane of Gram-negative bacteria: Structure and functions},
  author={O. Novikova and T. Solovyeva},
  journal={Biochemistry (Moscow) Supplement Series A: Membrane and Cell Biology},
The structure and functional properties of nonspecific porins (β-structured integral proteins of the outer membrane of Gram-negative bacteria) are overviewed. The characteristic features of porin spatial structure related to the principles of β-barrel construction and pore geometry are considered. The data concerning nonspecific diffusion of low-molecular substances and dynamic behavior of porin channels dependent on the distribution of charged amino acid residues in different structural… Expand

The Long and Winding Road for Symbiont and Yolk Protein to Host Oocyte
It is reported that, in some leafhoppers, a considerable proportion of Vg is incorporated into symbiotic bacteria and translocated into oocytes by hitchhiking the symbiont’s vertical transmission mechanism, uncovering the host’'s cooption of the Symbiont's oocyte-targeting machineries and highlighting complicated trajectories toward host-symbiont coevolution and integration.

Molecular architecture and electrostatic properties of a bacterial porin.
The x-ray structure of the integral membrane protein porin from Rhodobacter capsulatus has revealed details of its shape, the residue distributions within the pore and at the membrane-facing surface, and the location of calcium sites. Expand
Structure and functional mechanism of porins.
The high-resolution structure data from the bacterial porins are reviewed in the context of biophysical and biochemical observations and the molecular mechanisms responsible for the transport of solutes through porin channels are discussed. Expand
Crystal structures explain functional properties of two E. coli porins

Effects of pH on bacterial porin function.
Porin is a trimeric channel-forming protein in the outer membrane of Gram-negative bacteria and the presence of two or more pH-dependent substates of porin could explain the variability in pore diameter measured by others and suggests a more dynamic role for porin in the cell. Expand
General and specific porins from bacterial outer membranes.
The remarkable ability of maltoporin to allow translocation of long maltodextrin molecules through the small channel has been traced back to the presence of an elongated hydrophobic patch at the channel lining. Expand

Molecular basis of bacterial outer membrane permeability.
It is becoming increasingly clear that the outer membrane is very important in the physiology of gram-negative bacteria in making them resistant to host defense factors such as lysozyme, P-lysin, and various leukocyte proteins. Expand
Role of the constriction loop in the gating of outer membrane porin PhoE of Escherichia coli
Whereas the properties of several mutant channels were changed, all of these channels could still be closed at high potential, showing that a gross movement of the constriction loop within the channel is not implicated in voltage gating. Expand
