Chemotaxis in Escherichia coli
Cold Spring Harbor Symposia on Quantitative Biology, 1965 Motile bacteria are attracted to a variety of chemicals — a phenomenon called chemotaxis (for a review, see Weibull, 1960). Although chemotaxis by bacteria has been recognized since the end of the nineteenth century, thanks to the pioneering work of Engelmann, Pfeffer, and other biologists, the mechanisms involved are still almost entirely unknown.

FEBS Letters, EarlyView.The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.

Detection of Escherichia Coli Using PCR Analysis Without DNA Extraction
Folia Medica Indonesiana, 2021 This study aimed to detect Escherichia coli directly without DNA extraction. The nucleus membrane and cell membranes of the Escherichia coli are composed of a phospholipid bilayer, damaged if heated at 950C.

Unraveling Mycobacterium tuberculosis acid resistance and pH homeostasis mechanisms
FEBS Letters, EarlyView.Mycobacterium tuberculosis exhibits a remarkable resilience to acid stress. In this Review, we discuss some of the molecular mechanisms and metabolic pathways used by the tubercle bacilli to adapt and resist host‐mediated acid stress. Mycobacterium tuberculosis (Mtb) is a successful pathogen that has developed a variety of strategies to survive and ...

Novel Plasmid-Mediated Colistin Resistance Gene mcr-3 in Escherichia coli
mBio, 2017 The mobile colistin resistance gene mcr-1 has attracted global attention, as it heralds the breach of polymyxins, one of the last-resort antibiotics for the treatment of severe clinical infections caused by multidrug-resistant Gram-negative bacteria.

FEBS Letters, EarlyView.α2 → 8 polysialic acid elicits poor immunogenicity. Small‐angle scattering shows a supramolecular structure with parallel‐chain binding, although in different forms at μm and mm calcium. The major histocompatibility complex requires molecular weights around 2000 Da to produce antibodies, and 2000 Da polysialic oligomers will bind in these structures ...

CsrA and its regulators control the time-point of ColicinE2 release in Escherichia coli [PDF]
Scientific Reports 8, 6537 (2018), 2018 The bacterial SOS response is a cellular reaction to DNA damage, that, among other actions, triggers the expression of colicin - toxic bacteriocins in Escherichia coli that are released to kill close relatives competing for resources. However, it is largely unknown, how the complex network regulating toxin expression controls the time-point of toxin ...

Environmental Escherichia coli: ecology and public health implications—a review
Journal of Applied Microbiology, 2017 Escherichia coli is classified as a rod‐shaped, Gram‐negative bacterium in the family Enterobacteriaceae. The bacterium mainly inhabits the lower intestinal tract of warm‐blooded animals, including humans, and is often discharged into the environment ...

FEBS Letters, EarlyView.Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.

Diffusion properties of single FoF1-ATP synthases in a living bacterium unraveled by localization microscopy [PDF]
, 2012 FoF1-ATP synthases in Escherichia coli (E. coli) bacteria are membrane-bound enzymes which use an internal proton-driven rotary double motor to catalyze the synthesis of adenosine triphosphate (ATP). According to the 'chemiosmotic hypothesis', a series of proton pumps generate the necessary pH difference plus an electric potential across the bacterial ...
