Electric Field Induced Biomimetic Transmembrane Electron Transport using Carbon Nanotube Porins as Bipolar Electrodes [PDF]
, 2021 Cells modulate their homeostasis through the control of redox reactions via transmembrane electron transport systems. These are largely mediated via oxidoreductase enzymes. Their use in biology has been linked to a host of systems including reprogramming

The Optimal Permeation of Cyclic Boronates to Cross the Outer Membrane via the Porin Pathway
Antibiotics, 2022 We investigated the diffusion of three cyclic boronates formulated as beta-lactamase inhibitors through the porin OmpF to evaluate their potential to cross OM via the porin pathway.

Roles of the EnvZ/OmpR Two-Component System and Porins in Iron Acquisition in Escherichia coli
mBio, 2020 The work presented here solved a long-standing paradox of the negative effects of certain missense alleles of envZ, which codes for kinase of the EnvZ/OmpR two-component system, on the expression of ferric uptake genes.

Single-channel measurements of an N-acetylneuraminic acid-inducible outer membrane channel in Escherichia coli [PDF]
, 2012 NanC is an Escherichia coli outer membrane protein involved in sialic acid (Neu5Ac, i.e., N-acetylneuraminic acid) uptake. Expression of the NanC gene is induced and controlled by Neu5Ac. The transport mechanism of Neu5Ac is not known.
