Modelling bacterial flagellar growth

, 2011
The growth of bacterial flagellar filaments is a self-assembly process where flagellin molecules are transported through the narrow core of the flagellum and are added at the distal end.

Association between obesity and bacterial vaginosis as assessed by Nugent score [PDF]

, 2019
Background Bacterial vaginosis is one of the most common vaginal conditions in the U.S. Recent studies have suggested obese women have an abnormal microbiota reminiscent of BV; however, few studies have investigated the prevalence of bacterial vaginosis

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, EarlyView.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Onset of Shear Waves In A Bacterial Bath: A Novel Effect

, 2003
Recent experiments on particle diffusion in bacterial baths indicate the formation of correlated structures in the form of bacterial swirls. Here we predict that such a structural ordering would give rise to the new effect of propagating shear waves in a

The nicotinamide hypothesis revisited—plant defense signaling integrating PARP, nicotinamide, nicotinic acid, epigenetics, and glutathione

FEBS Letters, EarlyView.
Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

Rice straw increases microbial nitrogen fixation, bacterial and nifH genes abundance with the change of land use types

Frontiers in Microbiology
Soil microorganisms play an important role in soil ecosystems as the main decomposers of carbon and nitrogen. They have an indispensable impact on soil health, and any alterations in the levels of organic carbon and inorganic nitrogen can significantly ...

Structural dynamics of the plant hormone receptor ETR1 in a native‐like membrane environment

FEBS Letters, EarlyView.
The present study unveils the structural and signaling dynamics of ETR1, a key plant ethylene receptor. Using an optimized nanodisc system and solution NMR, we captured full‐length ETR1 in a native‐like membrane environment. Our findings reveal dynamic domain uncoupling and Cu(I)‐induced rigidification, providing the first evidence of metal‐triggered ...

Molecular Epidemiology of O139 Vibrio cholerae: Mutation, Lateral Gene Transfer, and Founder Flush

Emerging Infectious Diseases, 2003
Vibrio cholerae in O-group 139 was first isolated in 1992 and by 1993 had been found throughout the Indian subcontinent. This epidemic expansion probably resulted from a single source after a lateral gene transfer (LGT) event that changed the serotype of

Mechanistic basis for inhibition of the extended‐spectrum β‐lactamase GES‐1 by enmetazobactam and tazobactam

FEBS Letters, EarlyView.
Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation
