#SIRT7 is a histone deacetylase with highly specific activity on #chromatin substrates.
We just published mechanism-based #cryoEM structures of #SIRT7 on nucleosomes to understand its activity 👇

I am really excited that #CHEMTUBIO will be funded through an @erc.europa.eu Starting Grant!
This funding will kickstart my lab next year and help us unveil the mechanisms and therapeutic implications of erasers of microtubule modifications.
Stay tuned!

Pint of Science was again a great success in Lausanne, with >500 people attending our events!
Kudos to co-coordinators @miriamlisci.bsky.social and @juliensluneau.bsky.social, and to the fantastic team of 19 volunteers at the bars 🥳!

Check out our new study of chromatin ubiquitylation. @alexateslenko.bsky.social visualized directly at single molecule scale how vPRC1 ubiquitylates neighboring nucleosomes. These results suggest potential mechanism on how H2Aub domains are established. 👇👇👇

Single-molecule analysis reveals the mechanism of chromatin ubiquitylation by variant PRC1 complexes
Single-molecule experiments show that active conformation formation controls chromatin ubiquitylation kinetics by variant PRC1.

What started as the M.Sc. projects of Michaela Benová and Athanasios Tsiris, seeking potent and selective inhibition of #HDAC11, turned into a great collaboration between the labs of @christianaolsen.bsky.social and Christian Heinis led by @danieladankova.bsky.social.

Big congratulations, Daniela!

Thank you as well to @snsf-ch.bsky.social and IRFD for funding my postdoc at EPFL, to the @swisschemistry.bsky.social foundation and La Caixa Foundation for supporting Polina and Esther, and other funding from @snsf-ch.bsky.social, EPFL and the Dubochet Center for Imaging.

This would not have been possible without the excellent (and very efficient!) contributions of Babatunde Ekundayo and Polina Foteva (who just defended her MSc thesis 🥳), of Dongchun Ni, Esther Calviño and Henning Stahlberg, or without the truly supportive guidance of @beatfierz.bsky.social.

The contacts of the catalytic domain with DNA, on the other hand, are responsible for maintaining #H3K36ac selectivity.
Mutating a key interacting loop helps release the enzyme from the nucleosome and become much more active on #H3K18ac substrates 🤯.

carlosmyruela.bsky.social
The multivalent interactions of the nucleosome-binding domain are important for both activities, especially to find #chromatin substrates in an environment full of nucleic acids.
Interestingly, this domain is only present in insects and most vertebrates.

carlosmyruela.bsky.social
By comparing structures trapped at each substrate position we could rationalize its activity and intrinsic selectivity 🔍.
#SIRT7 binding is optimal for targeting #H3K36ac, and it can only access #H3K18ac through partial disengagement from the nucleosome and DNA bending.

Babatunde Ekundayo generated beautiful high-resolution structures, where we identified:
- A unique N-terminal nucleosome-binding domain, which places the #SIRT7 catalytic domain by the H3 tail exit site
- Extensive contacts with the two DNA gyres!

We produced nucleosomes with a thiourea mechanism-based handle (MTU) at the H3K18 and H3K36 preferred substrate positions, through histone semi-synthesis and reconstitution in vitro.
This allowed us to stabilize specific enzyme:substrate complexes efficiently for #cryoEM.
