Review updates bacteriocin classification in Lactobacillaceae
—
What the study found The authors report that Lactobacillaceae produce many bacteriocins, which are ribosomally synthesized antimicrobial peptides, and that some of these molecules are post-translationally modified. They also identify 474 individual bacteriocins reported in Lactobacillaceae to date. Why the authors say this matters The study suggests that Lactobacillaceae have broad biotechnological potential in food,…
Mycobacterial gyrase inhibition depends on DNA topology
Study reveals that antibacterial drugs inhibit different gyrase-mediated catalytic activities at varying concentrations, with DNA topology modulating drug potency beyond DNA cleavage mechanisms.
