DNA damage response and cell cycle regulation in bacteria: a twist around the paradigm
Frontiers in MicrobiologyThe co-protease activity in the RecA-ssDNA complex cleaves the autorepressor LexA, resulting in the derepression of a large number of genes under LexA control.

Bacteria under SOS evolve anticancer phenotypes
Infectious Agents and Cancer, 2010 Background The anticancer drugs, such as DNA replication inhibitors, stimulate bacterial adhesion and induce the bacterial SOS response. As a variety of bacterial mutants can be generated during SOS, novel phenotypes are likely to be selected under the ...

Advanced Materials, EarlyView.TGTMW fibers are designed to show a sharp resistance increase under pressure, as the multi‐wall structure in the transition region between compressed and uncompressed areas bends and forms microcracks. This design breaks the physical sensitivity limit of conventional fiber‐shaped pressure sensors, which usually show resistance reduction under pressure ...

Redesign of ultrasensitive and robust RecA gene circuit to sense DNA damage
Microbial Biotechnology, 2021 Summary SOS box of the recA promoter, PVRecA from Vibrio natriegens was characterized, cloned and expressed in a probiotic strain E. coli Nissle 1917. This promoter was then rationally engineered according to predicted interactions between LexA repressor

Aeons of distress : an evolutionary perspective on the bacterial SOS response [PDF]
, 2007 The SOS response of bacteria is a global regulatory network targeted at addressing DNA damage. Governed by the products of the lexA and recA genes, it co-ordinates a comprehensive response against DNA lesions and its description in Escherichia coli has ...

Surface Oxidation of 2D γ‐Indium Sulfide Nanoplatelets and Its Impact on Photoluminescence
Advanced Photonics Research, EarlyView.Photoluminescence of defective 2D γ‐In2S3 can be modulated after exposure to air or oxygen‐containing ligands. Cryogenic photoluminescence measurements reveal that a new acceptor level is introduced upon oxidation, modulating the relative intensity of the emission bands.
