Flavin-containing monooxygenases: mutations, disease and drug response.
Flavin-containing monooxygenases (FMOs) metabolize numerous foreign chemicals, including drugs, pesticides and dietary components and, thus, mediate interactions between humans and their chemical environment. We describe the mechanism of action of FMOs and insights gained from the structure of yeast FMO. We then concentrate on the three FMOs (FMOs 1, 2 and 3) that are most important for metabol...
متن کاملGenetic Variants of Flavin-containing Monooxygenases: Consequences for Drug Metabolism
The metabolism of the anti-tubercular drug, thiacetazone (TAZ) by human FMOs in vitro and the disposition of TAZ in vivo in mice were studied. Reverse phase chromatography confirmed TAZ to be a substrate for human FMO1, FMO2.1 and FMO3 with the formation of TAZ-sulphinic acid and TAZ-carbodiimide via a TAZsulphenic acid intermediate. The products are the same as those formed by the Mycobacteriu...
متن کاملFlavin Containing Monooxygenases and Metabolism of Xenobiotics
Bu derlemede flavin-içeren monooksijenazların (FMO) farmakolojik ve toksikolojik önemi ile ilgili güncel bilgiler özetlenmiştir. FMO’lar nükleofilik hetereatom içeren ksenobiyotiklerin ve ilaçların oksidasyonuna katılan mikrozomal bir enzim ailesidir. FMO’ların ilaç metabolizmasındaki etkinlikleri ve hastalıklarla olan ilişkileri, daha fazla araştırılması gereken alanlardır. FMO’lar üzerine yap...
متن کاملStructure-function of cytochromes P450 and flavin-containing monooxygenases: implications for drug metabolism.
This article is a report on a symposium held at Experimental Biology '98 in San Francisco, California. Recent developments in site-directed mutagenesis, computer-modeling, and mechanistic analysis of cytochromes P450 and flavin-containing monooxygenases are described. A unifying theme is the elaboration of general approaches for understanding and predicting the function of individual forms of t...
متن کاملMicrobial Flavoprotein Monooxygenases as Mimics of Mammalian Flavin-Containing Monooxygenases for the Enantioselective Preparation of Drug Metabolites.
Mammalian flavin-containing monooxygenases, which are difficult to obtain and study, play a major role in detoxifying various xenobiotics. To provide alternative biocatalytic tools to generate flavin-containing monooxygenases (FMO)-derived drug metabolites, a collection of microbial flavoprotein monooxygenases, sequence-related to human FMOs, was tested for their ability to oxidize a set of xen...
