As a member of the @igemcommunity.bsky.social Engineering Committee I received additional small grants to extend these toolkits both of which are now in over 50 countries around the world. Congratulations to the four other recipients. |5/5|

Yeast Protein Expression Toolkit to permit engineering of the “non-conventional” oleaginous yeast species Yarrowia lipolytica. Imagine one universal toolkit for all of the common industrial and research yeast species. ...2/5
The Yeast Protein Expression Toolkit extend the Open Yeast Collection by offering a library of DNA parts for adding protein fusion tags, including secretion signals, purification tags, linkers, fluorescent proteins and protease cleavages sites.

A big thank you to RootPath and its reviewers on selecting my project for the inaugural #MegabaseSpark competition. 100kbp of free rBlock DNA synthesis is very significant. I am very excited to put this win to good use in extending Open Yeast Collection (OYC) and the ...1/5
The Open Yeast Collection (OYC) is an open DNA toolkit released under the OpenMTA for engineering yeast. It is a library of DNA parts that can be assembled into constructs to produce proteins or develop metabolic pathways in yeast.

Related but cool combo of cytogenetics and phenotype. Know when the first QTL was mapped?

A reminder you/your lab can support FlyBase at Cambridge through the following link. Every bit helps. Please share if you yourself can't donate.

This tool is great. I’d love it even more if I can compare the long read assembly that I have with an NCBI reference genome! Seems to only take NCBI genomes for comparisons.

Very sad news. I was building HMMER profiles to mine the nascent Celera mouse and human genomes. Such a powerful tool.

We’ve uncovered Asgard chromatin structures formed by a Hodarchaeal histone : closed hypernucleosome conserved in archaea and an open form resembling the H3-H4 eukaryotic octasome. Fantastic work by @harshranawat.bsky.social!

AlphaFold is amazing but gives you static structures 🧊

In a fantastic teamwork, @mcagiada.bsky.social and @emilthomasen.bsky.social developed AF2χ to generate conformational ensembles representing side-chain dynamics using AF2 💃

Re DNA sequence DBs: While sequence is shared across #INSDC databases #ENA #Genbank #DDBJ, the presentation and granularity of annotations/metadata can differ notably, with diff. benefits, impacting searches and downstream analyses. All INSDC databases must be maintained - annotations are important

Delighted to share our latest paper describing a method to read the levels of hundreds of metabolites or drugs in parallel using DNA sequencing. This method, which we call ‘smol-seq’ (Small MOLecule sequencing), harnesses the power of DNA sequencing for metabolite detection:
