Again thanks for highlighting, but the text refers to a completely different paper. We engineered a polyphosphate kinase to produce base-modified GTP and ATP analogues!

Thanks to Rachel, @raschere.bsky.social, Ann-Marie, Jannik, Aileen, @rentmeisterlab.bsky.social and Daniel!

We systematically studied the substrate preferences of EbPPK2, determined the first crystal structure of the enzyme and used structure-guided engineering to enable efficient access to base-modified GTP and ATP analogues. #ChemSky #ChemBio

A baby platypus is called a puggle (or 'platypup' 😁)

And anytime you post a video like this one, someone always points out they have venomous spurs.

The adult males DO, but *only* the adult males!

Let's talk about the amazing venom cocktail produced by this adorable little beaver-duck.

This would be a an option.

With chimeric cofactors, we can turn methyltransferases into prenyltransferases. Methyltransferases even prefer AdoPrenyl!Thanks to co-first author Arne and the team led by Andrea

CRISPR screening reveals TRIM25 as a pH-sensitive sensor that specifically targets foreign RNAs entering through endosomes. N1-methylpseudouridine helps repel TRIM25 binding & enhances protein production.

"So ein herrlicher Tag, und ich soll gehen. Aber was liegt an unserem Leben, wenn wir es damit schaffen, Tausende von Menschen aufzurütteln und wachzurütteln" (Sophie Scholl)

Heute vor 82 Jahren wurden Sophie Scholl, Hans Scholl und Christoph Probst von den Nazis ermordet.

Just a reminder that Germany was the center of scientific progress until the Nazis suppressed, drove away, or killed all the non-Nazi scientists.

The ACS has deleted its website on Diversity, Equity, Inclusion & Respect. And with that move, have shown they are worthy of none of the latter.
People ask why no-one stands up to fascists, this is why - they are too worried about their own standing to challenge it.

🧪Science breakthrough of the year - a mindblowing example of the value of interdisciplinary approaches and a testament to the value of fundamental research:

We tested the ability of a SAM riboswitch to detect 17 in situ generated SAM analogues. Just accepted in ChemComm! Thanks to my former colleagues Jonas, Aileen and Arne in the Rentmeister Lab and especially to Andrea for her constant support. #ChemSky #ChemBio

In July, I published my first paper on the chemo-enzymatic generation of base-modified ATP analogues! These can then be used to generate hypermodified poly(A) tails. Thanks to all the people involved!

Ok, so if you’re an organic chemist you’ve done chiral GC-MS. What if you could drop the GC, and just measure enantiomeric ratio by MS? That’s what’s in SCIENCE today from Xiaoyu Zhou and coworkers in Zheng Ouyang’s group. Have a look:

Thanks Pavel!

Hi Bluesky,
over the last years I was working on the biocatalytic generation of SAM analogues to expand the scope of methyltransferases. Selective 4-chlorobenzylation on the mRNA 5′ cap could improve protein production in human cell lines.
