In Escherichia coli, levels of the two major outer membrane porin proteins, OmpF and
OmpC, are regulated in response to a variety of environmental parameters, and numerous …

It is quite important to understand the overall metabolic regulation mechanism of bacterial
cells such as Escherichia coli from both science (such as biochemistry) and engineering …

The mechanism (s) of how bacteria acquire tolerance and then resistance to antibiotics
remains poorly understood. Here, we show that glucose abundance decreases …

Light-switchable proteins enable unparalleled control of molecular biological processes in
live organisms. Previously, we have engineered red/far-red and green/red photoreversible …

Tolerance to acidic environments is an important property of free-living and pathogenic
enteric bacteria. Salmonella enterica serovar Typhimurium possesses two general forms of …

Salmonella enterica serovar Typhimurium periodically experiences acid stress in a variety of
host and non‐host environments. An encounter with non‐lethal acid stress (pH> 4) induces …

Bacterial morphology is a complex trait that is highly sensitive to changes in the
environment. For heterotrophic organisms, such as Escherichia coli, increases in nutrient …

Expression of the major outer-membrane porins in Escherichia coli is transcriptionally
controlled during nutrient limitation. Expression of ompF was more than 40-fold higher under …

Background The cAMP receptor protein (CRP) is a global bacterial regulator that controls
many target genes. The CRP-cAMP complex regulates the ompR-envZ operon in E. coli …

Our understanding of porin regulation has revealed not only increasing complexity in the
regulatory mechanisms, but also that the porin repertoire is more extensive than previously …
