Substrate Promiscuity of a Paralytic Shellfish Toxin Amidinotransferase [PDF]
ACS Chemical Biology, 2020 Secondary metabolites are assembled by enzymes that often perform reactions with high selectivity and specificity. Many of these enzymes also tolerate variations in substrate structure, exhibiting promiscuity that enables various applications of a given biocatalyst.

C–H Hydroxylation in Paralytic Shellfish Toxin Biosynthesis [PDF]
Journal of the American Chemical Society, 2018 The remarkable degree of synthetic selectivity found in Nature is exemplified by the biosynthesis of paralytic shellfish toxins such as saxitoxin. The polycyclic core shared by saxitoxin and its relatives is assembled and subsequently elaborated through the installation of hydroxyl groups with exquisite precision that is not possible to replicate with ...
