inhibit sulfatases. The MbI motifs were based on simple aromatic sulfates, which are known to be commonly accepted substrates across this highly conserved enzyme class, so that they might be generally useful for sulfatase labeling studies. (Difluoro)methyl phenol sulfate analogs, constructed to release a reactive quinone methide trap, were not capable of irreversibly inactivating the sulfatase active

Plugged up: A rapid and efficient cascade of desulfatation, oxidation, and cross‐linking mediates wound sealing in the giant‐celled algaDasycladusvermicularis (see picture). UV and fluorescence studies and mass spectrometry show the wound plug is a coumarin‐based polymer.

commonly used arylsulfatase extracted from the snail Helix pomatia. In the past, this enzyme has been used in the form of a crude mixture of enzymes, however, recently we have purified this sulfatase for a new application in metabolomics-driven discovery of sulfated metabolites. To evaluate the substratespecificity of this promiscuous sulfatase, we have synthesized a series of new sulfated metabolites

through metabolic interaction. Selective investigation of the co-metabolism of bacteria and their human host is a challenging task and methods for their analysis are limited. One class of metabolites associated with this co-metabolism are O-sulfated compounds. Herein, we describe the development of a new enzymatic assay for the selective massspectrometricinvestigation of this phase II modification class
