At the same time, for mid-size datasets (most frequent use case), BiG-SCAPE v2 approaches the speed of BiG-SLiCE. For larger datasets, BiG-SCAPE has become more resource-efficient, which now allowed us to analyse >250k BGCs (the antiSMASH database) with it in just a few days on a compute server.

Benchmarking on several different types of ground truth datasets shows the increases in accuracy, with BiG-SLiCE v2 often matching BiG-SCAPE v1 accuracy, and BiG-SCAPE v2 combining its speed increase with a small but notable accuracy gain as well.

BiG-SCAPE was completely rewritten from scratch over the past few years, and now features new alignment modes, a more prominent query mode (which allows you to search genomes from a single BGC query) and more scalable interactive visualizations and data selection/filtering.

Of course I see your general point. Admiring something does not mean I suggest mindlessly emulating it, although it would be arrogant to deny there is a lot we can learn from how people do things in other corners of the world, like China; see e.g. also the speed of transport electrification there.

Discovery and Heterologous Expression of the Soil Metagenome-Derived Lasso Peptide Metanodin with an Unprecedented Ring Structure Culture-independent metagenomic approaches have proven to be effective tools for identifying previously hidden biosynthetic gene clusters (BGCs) encoding novel natural products with potential medical relevance. However, producing these compounds remains challenging as metagenomic BGCs often originate from organisms phylogenetically distant from available heterologous hosts. Lasso peptides, a subclass of ribosomally synthesized and post-translationally modified peptide (RiPP) natural products, exhibit diverse bioactivities, yet no lasso peptide has previously been discovered directly from a metagenome. Here, we report the discovery and heterologous expression of the first soil metagenome-derived lasso peptide. Expression of its biosynthetic gene cluster in Escherichia coli, followed by mass spectrometry analysis, strongly supported the predicted amino acid sequence and lasso structure of the peptide. Notably, this lasso peptide is the first to feature asparagine as the ring-forming residue at position one. Taxonomic analysis of the corresponding BGC identified an uncultivated member of the Steroidobacterales family (Gammaproteobacteria) as the closest known relative of the potential native host. These findings underscore the potential of metagenomic genome mining to reveal structurally novel RiPPs and to expand our understanding of the natural diversity of lasso peptides.

Happy to share our newest manuscript about the discovery and hererologous expression of metanodin, a new lassopeptide with unprecedented structural features directly from soil metagenomes. pubs.acs.org/doi/full/10....

Polyunsaturated fatty acid (PUFA) synthase enzymes turn out to be far more versatile than we ever imagined! In our new preprint, we reveal a largely untapped biosynthetic space where they team up with PKSs and NRPSs to create new types of bioactive amphiphilic metabolites.
