Kinome rewiring reveals AURKA limits PI3K-pathway inhibitor efficacy in breast cancer

Kinome rewiring reveals AURKA limits PI3K-pathway inhibitor efficacy in breast cancer, Published online: 25 June 2018; doi:10.1038/s41589-018-0081-9

Proteomic mapping of dynamic changes in kinase signaling after drug treatment identifies that AURKA inhibition is required for drug sensitivity, representing a new co-targeting opportunity with PI3K, AKT, or mTOR inhibitors in breast cancer.

Cleavage of a carbon–fluorine bond by an engineered cysteine dioxygenase, Published online: 25 June 2018; doi:10.1038/s41589-018-0085-5

Engineered variants of cysteine dioxygenase containing a halogen-substituted tyrosine analog provide insights into the process of Cys–Tyr cross-link formation and indicate that the enzyme can catalyze oxidative cleavage of a carbon–fluorine bond.

Metabolic engineering of a carbapenem antibiotic synthesis pathway in Escherichia coli

Metabolic engineering of a carbapenem antibiotic synthesis pathway in <i>Escherichia coli</i>, Published online: 25 June 2018; doi:10.1038/s41589-018-0084-6

Efficient production of a simple carbapenem antibiotic in Escherichia coli is achieved by a combination of feedback-resistant enzymes for increased precursor biosynthesis and inhibition of fatty acid synthesis for tolerance toward the toxic product.

Sarpagan bridge enzyme has substrate-controlled cyclization and aromatization modes

Sarpagan bridge enzyme has substrate-controlled cyclization and aromatization modes, Published online: 25 June 2018; doi:10.1038/s41589-018-0078-4

Three homologous cytochrome P450s from monoterpene indole alkaloid-producing plants enable the identification of sarpagan bridge enzyme, which catalyzes either cyclization or aromatization to yield sarpagan or β-carboline alkaloids, respectively.
