Following up on our ChemBioChem paper, we now published an in depth protocol that describes and evulates the incorporation of non-natural amino acids into proteins expressed in human cells for subsequent small-scale purification and fluorescence labelling via different bioorthogonal chemistries in detail.

Our paper "Molecular force spectroscopy with a DNA origami based nanoscopic force clamp" (published in Science http://science.sciencemag.org/content/354/6310/305 won the CeNS Publication Award 2017 for the best interdisciplinary publication. We are grateful for the fantastic collaboration with the Tinnefeld lab and Liedl lab that made this interdisciplinary work possible.

Nature Microbiology celebrates the 40th anniversary of the seminal publication by Woese and Fox introducing the third domain of life, Archaea. You can find the "40 years of Archaea" channel here https://naturemicrobiologycommunity.nature.com/channels/1431-40-years-of-archaea. Among other researchers in the archaeal field, Prof. Dr. Dina Grohmann contributed to the anniversary channel and you can find her Snapshot interview here https://naturemicrobiologycommunity.nature.com/channels/1431-40-years-of-archaea/posts/22139-snapshot-dr-dina-grohmann

Multicellular organisms have a sophisticated immune system encompassing many specialised cell types like macrophages or T cells to fend off attackers (e.g. viruses or bacteria). But how do unicellular organisms like archaea defend themselves against invaders? Our latest study provides insights in the defence mechanisms of the archaeal organisms M. jannaschii, which utilises the so-called Argonaute protein to degrade foreign genetic material and to use its guide-independent activity to prime Argonaute for sequence-specific action. We are especially happy that we could publish this story back-to-back with our structural characterisation of this archaeal Argonaute variant. see press release:

The development of a new type of DNA origami-based force clamp by the Liedl and Tinnefeld groups allowed us to probe the force dependency of TBP-dependent DNA bending. The results are published in: Nickels P.C., Wünsch B., Holzmeister P., Bae W., Kneer L.M., Grohmann D., Tinnefeld P. and Liedl T. (2016), Molecular Force Spectroscopy with a DNA Origami-Based Nanoscopic Force Clamp. Science. 354(6310):305-307.
