Physical Model of the Immune Response of Bacteria Against Bacteriophage Through the Adaptive CRISPR-Cas Immune System [PDF]
, 2013 Bacteria and archaea have evolved an adaptive, heritable immune system that recognizes and protects against viruses or plasmids. This system, known as the CRISPR-Cas system, allows the host to recognize and incorporate short foreign DNA or RNA sequences,

FEBS Letters, EarlyView.This work presents the characterization of MvoDUF2193, a Methanococcus voltae (Mvo) protein from the domain of unknown function (DUF) 2193 family. We demonstrate that MvoDUF2193 binds a single [4Fe–4S] cluster per subunit and that cluster occupancy regulates the transition from an apo tetramer to a [4Fe–4S] monomeric form. This structural transition is

Epidemiology and Diagnostics of Carbapenem Resistance in Gram-negative Bacteria
Clinical Infectious Diseases, 2019 Carbapenem resistance in gram-negative bacteria has caused a global epidemic that continues to grow. Although carbapenemase-producing Enterobacteriaceae have received the most attention because resistance was first reported in these pathogens in the ...

Vertebrate Hosts as Islands: Dynamics of Selection, Immigration, Loss, Persistence, and Potential Function of Bacteria on Salamander Skin. [PDF]
, 2016 Skin bacterial communities can protect amphibians from a fungal pathogen; however, little is known about how these communities are maintained. We used a neutral model of community ecology to identify bacteria that are maintained on salamanders by ...

FEBS Letters, EarlyView.In this work, we reveal how different enzyme binding configurations influence the fluorescence decay of NAD(P)H in live cells using time‐resolved anisotropy imaging and fluorescence lifetime imaging microscopy (FLIM). Mathematical modelling shows that the redox states of the NAD and NADP pools govern these configurations, shaping their fluorescence ...

Combatting antibiotic-resistant bacteria using nanomaterials.
Chemical Society Reviews, 2019 The dramatic increase in antimicrobial resistance for pathogenic bacteria constitutes a key threat to human health. The Centers for Disease Control and Prevention has recently stated that the world is on the verge of entering the "post-antibiotic era ...

PRODUCTION AND CHARACTERIZATION OF CRUDE INTRACELLULER PHYTASE FROM RECOMBINANT BACTERIA pEAS1AMP [PDF]
, 2009 This research was aimed at producing a crude intracellular phytase characterized from recombinant bacteria. The recombinant bacteria (pEAS1AMP) was produced by way of transforming pET-22b(+) +pEAS1 into competent E. coli BL21 and E.
