The narrowing prokaryote–eukaryote divide reveals a complexity spectrum
Cellular organisms can be divided into two basic types of cells: the prokaryotic cells of Bacteria and Archaea and the eukaryotic cells. The rapidly expanding knowledge of the diversity and ultrastructure of prokaryotic cells has revealed cellular intricacies that warrant a critical reappraisal of the profundity of the prokaryote–eukaryote divide.

I'm excited that this collaborative work with Alan @acartmell47.bsky.social is finally out. We have developed some powerful tools to study carbohydrate sulfatases (a tricky class of enzyme!) and shown how they can be used with enzymes from host-associated bacteria.
