Structural basis for divergent C–H hydroxylation selectivity in two Rieske oxygenases
Rieske oxygenases are iron-dependent enzymes that catalyse C–H mono- and dihydroxylation reactions. Here, the authors characterise two cyanobacterial Rieske oxygenases, SxtT and GxtA that are involved in the biosynthesis of paralytic shellfish toxins and determine their substrate free and saxitoxin...

description | Rieske oxygenases are iron-dependent enzymes that catalyse C–H mono- and dihydroxylation reactions. Here, the authors characterise two cyanobacterial Rieske oxygenases, SxtT and GxtA that are involved in the biosynthesis of paralytic shellfish toxins and determine their substrate free and saxitoxin analog-bound crystal structures and by using mutagenesis experiments identify residues, which are important for substrate positioning and reaction selectivity. |
