Enzyme Kinetics of Organic Contaminant Oxygenations
CHIMIA, 2020 Enzymatic oxygenations initiate biodegradation processes of many organic soil and water contaminants. Even though many biochemical aspects of oxygenation reactions are well-known, quantifying rates of oxidative contaminant removal as well as the extent ...

Design principles for site-selective hydroxylation by a Rieske oxygenase
Nature Communications, 2022 SxtT and GxtA are Rieske oxygenases that are involved in paralytic shellfish toxin biosynthesis and catalyze monohydroxylation reactions at different positions on the toxin scaffold.

ENGINEERING NON-HEME MONO- AND DIOXYGENASES FOR BIOCATALYSIS
Computational and Structural Biotechnology Journal, 2012 Oxygenases are ubiquitous enzymes that catalyze the introduction of one or two oxygen atoms to unreactive chemical compounds. They require reduction equivalents from NADH or NADPH and comprise metal ions, metal ion complexes, or coenzymes in their active

Conservation of the unusual dimeric JmjC fold of JMJD7 from Drosophila melanogaster to humans
Scientific Reports, 2022 The JmjC family of 2-oxoglutarate dependent oxygenases catalyse a range of hydroxylation and demethylation reactions in humans and other animals. Jumonji domain-containing 7 (JMJD7) is a JmjC (3S)-lysyl-hydroxylase that catalyses the modification of ...

Palmitoylation of Metazoan Carotenoid Oxygenases
Molecules, 2020 Abundant in nature, carotenoids are a class of fat-soluble pigments with a polyene tetraterpenoid structure. They possess antioxidant properties and their consumption leads to certain health benefits in humans. Carotenoid cleavage oxygenases (CCOs) are a

Spin-orbit coupling effects in O(2) activation by cofactor-independent 2,4-dioxygenase [PDF]
The Ukrainian Biochemical Journal, 2019 The O2 (dioxygen) is paramagnetic molecule with two non-paired electron spins and triplet ground state (S = 1) while majority of organic molecules are diamagnetic species; they have all electron spins paired and the singlet ground state with the total ...

Structural basis for divergent C–H hydroxylation selectivity in two Rieske oxygenases
Nature Communications, 2020 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
