Highly specific mRNA cleavage by the MazF endoribonuclease orchestrates stationary transcriptome remodeling and rapid regrowth in Gram-positive bacteria

Regev Frenkel, Shira Omer Bendori, Tom Borenstein, Bar Tenennbaum, Shani Shalev, Nadejda Sigal, Y C Li, Polina Guler, Avigail Zarzar, José R. Penadés, Avigdor Eldar

This study shows that MazF toxin in Gram-positive bacteria specifically cleaves mRNAs to regulate stress response and enable rapid regrowth.

A prophage-encoded anti-phage defense system that prevents phage DNA packaging by targeting the terminase complex

Gil Azulay, Nadejda Sigal, Keren Tzohar Rabinovich, Dan Koenigsfeld, Olga Stadnyuk, Avijit Das, Polina Lisitzin, Einat Biderman, Ilya Borovok, Anat A. Herskovits

The paper identifies a prophage-encoded anti-phage defense system in Listeria monocytogenes that prevents phage DNA packaging by targeting the terminase complex, without halting the lytic cycle.
