The stereoselective metabolism of lansoprazole enantiomers was evaluated by incubation of human liver microsomes and cDNA-expressed cytochrome p450 (p450) enzymes to understand and predict their stereoselective disposition in humans in vivo. The intrinsic clearances (Clint) of the formation of both hydroxy and sulfone metabolites from S-lansoprazole were 4.9- and 2.4-fold higher than those from...

The baculovirus expression vector system was used to overexpress human FMO3 in insect cells for catalytic, structural, and immunochemical studies. Membranes prepared from infected Trichoplusia ni cell suspensions catalyzed NADPH-dependent metabolism of methyl p-tolyl sulfide at rates 20 times faster than those obtained with detergent-solubilized human liver microsomes. Sulfoxidation of the meth...

Flavoprotein-Monooxygenasen sind eine vielseitige Gruppe von Enzymen für biokatalytische Reaktionen. Die dazugehörigen Monooxygenasen der E (GEMs) katalysieren enantioselektive Epoxidierungs- und Sulfoxidierungsreaktionen. In dieser Arbeit beschreiben wir die Kristallstruktur einer Indol-Monooxygenase aus dem Bakterium Variovorax paradoxus EPS, GEM mit Bezeichnung VpIndA1. Basierend auf Substra...
