A CRISPR screen identifies a pathway required for paraquat-induced cell death

A CRISPR screen identifies a pathway required for paraquat-induced cell death, Published online: 23 October 2017; doi:10.1038/nchembio.2499

NatureArticleSnippet(type=short-summary, markup=

A positive-selection CRISPR screen with the pro-oxidant paraquat (PQ) uncovers three genes mediating PQ-induced cell death: POR is the source of PQ-mediated reactive oxygen species (ROS) generation, and ATP7A and SLC45A4 promote oxidant-dependent cell death.

Drug discovery: Controlling protein SUMOylation

Nature Chemical Biology, Published online: 18 October 2017; doi:10.1038/nchembio.2496

A potent and selective inhibitor of protein SUMOylation, a ubiquitin-like post-translational modification, has been developed, shedding light on the potential for developing new classes of anticancer therapeutics.

Biosynthesis: SAM cycles up for colibactin

September 19th, 2017 by Steven G Van Lanen

Nature Chemical Biology 13, 1059 (2017). doi:10.1038/nchembio.2479

Author: Steven G Van Lanen

The introduction of a cyclopropyl group is critical for imparting colibactin with the ability to cleave DNA. Nonribosomal peptide synthetase ClbH and polyketide synthase ClbI are now shown to work in concert to convert S-adenosylmethionine into this cyclopropyl group.
