Oxidative demethylation of algal carbohydrates by cytochrome P450 monooxygenases

Oxidative demethylation of algal carbohydrates by cytochrome P450 monooxygenases, Published online: 19 February 2018; doi:10.1038/s41589-018-0005-8

The discovery of cytochrome P450 monooxygenases that catalyze oxidative demethylation of 6-O-methyl-d-galactose reveals a new activity of cytochrome P450 enzymes and their role in polysaccharide biomass degradation in marine bacteria.

RNA structure: A LASER-focused view into cells

RNA structure: A LASER-focused view into cells, Published online: 14 February 2018; doi:10.1038/nchembio.2570

RNA structure is irrevocably linked to function. A new method, termed 'LASER', utilizes a light-activated chemical probe to query RNA tertiary structure and illuminate RNA–protein interactions in the living cell.

The ABCs of PTMs, Published online: 14 February 2018; doi:10.1038/nchembio.2572

Post-translational modifications (PTMs) are ubiquitous in all forms of life and often modulate critical protein functions. Recent chemical and biological advances have finally enabled scientists to precisely modify proteins at physiologically relevant positions, ushering in a new era of protein studies.

Protein evolution: Hacking an enzyme

Protein evolution: Hacking an enzyme, Published online: 14 February 2018; doi:10.1038/nchembio.2574

Early stages of protein evolution are inherently difficult to study. Genetic selection in Escherichia coli has now identified a life-sustaining de novo enzyme arising from a simple scaffold that is completely different from the native enzyme.
