Finally fixed some issues with PTMs for the PAE Viewer! Instead of the per-atom PAE which #AlphaFold outputs for modified amino acids, the average per-residue PAE is now displayed. subtiwiki.uni-goettingen.de/…

Now you can also find me on @bluesky (bsky.app/profile/c-elfmann.b…) and @joinmastodon (academiccloud.social/@elfman…)!

Try out our integration of the amazing protein structure search tool #Foldseek on #SubtiWiki (subtiwiki.uni-goettingen.de/…)! Just upload a structure or use PDB/AlphaFoldDB entries to find similar structures. @IMPRS_GS @uniGoettingen #alphafold #bacillus #subtilis
A screenshot of the results table of a Foldseek search on SubtiWiki. It shows multiple entries and corresponding metrics. One of the rows is expanded, revealing a 3D visualization of a superimposition of the target and the query structure corresponding to the search hit.

Thanks a lot to Michel van Kempen, Stephanie Kim, @schnamori, @SoedingL, and @thesteinegger for the development of Foldseek! Also check out the fantastic search.foldseek.com by @milot_mirdita, which we used as a blueprint. It boosts more options and detailed evaluation!

And of course many thanks to @clmgilchrist and Woosub Kim for their work on the search server and on Foldseek-Multimer, respectively, which was used in our implementation!

The PAE Viewer (subtiwiki.uni-goettingen.de/…) now supports evaluation of ligands and PTMs in your AlphaFold predictions, and the display of DNAs/RNAs is improved! @IMPRS_GS @uniGoettingen #alphafold #subtiwiki
Screenshot of the PAE Viewer web page. A complex structure is displayed, which contains the protein DnaA of Bacillus subtilis, ATP, and a DNA double strand encoding the DnaA box. The page shows the sequence of amino acids, atoms and nucleotides, a 3D rendering of the structure, and a matrix of the PAE. A selection was performed using the interactive PAE matrix, and thus the corresponding parts of the structure are highlighted in the sequences and 3D display.

I've created an offline version of the PAE Viewer with a basic CLI via Python, which you can use in your scripts. It just takes the input and opens the page in the browser with the data preloaded. Check out the new "Offline version" tab for instructions! subtiwiki.uni-goettingen.de/…

Proudly announcing the early release of SubtiWiki v5 (subtiwiki.uni-goettingen.de/)! It has many new features which we hope you'll like. It also still might have some bugs / missing data, so please don't hesitate to let us know! #subtiwiki #bacillus #subtilis @IMPRS_GS @JorgStulke

Don't worry if you're missing some features in this newest version, the last version is still accessible. Editing of data is also currently only possible in the last version. Many thanks to @VincenzDuMont, Tim van den Berg, Tom Nowak, Janne Pauline Winsemann and many more!

Check out the new BLAST search for SubtiWiki's new beta release: subtiwiki.uni-goettingen.de/…! You can now BLAST your nucleotide/protein sequence against SubtiWiki's coding sequences. Thank you Dmytro Boiko from @UAM_Poznan for your work on it! #subtiwiki #bacillus
Screenshot of the new BLAST search page on SubtiWiki v5 beta. A form with the query sequence as well as a table of hits with alignments is shown.
