Flavin-containing monooxygenase 3 (FMO3) is an enzyme that in humans is encoded by the FMO3 gene. It is part of the flavin-containing monooxygenase family of enzymes.

Pronunciation

The pronunciation of Flavin-containing monooxygenase 3 is: /ˈflævɪn kənˈteɪnɪŋ ˌmɒnəʊˈɒksɪdeɪs ˈθriː/

Etymology

The term "Flavin" is derived from Latin flavus, meaning "yellow". This is due to the yellow color of riboflavin, a type of flavin. "Monooxygenase" refers to the type of reaction the enzyme catalyzes, specifically the incorporation of one atom of oxygen into the organic substrate.

Function

FMO3 is an important enzyme in the metabolism of a wide variety of xenobiotics such as therapeutic drugs, dietary compounds, and environmental pollutants. It is primarily found in the liver and, to a lesser extent, in the kidney, lung, and intestine.
