WebMost flavoprotein monooxygenases are able to use molecular oxygen (O 2) as oxygen donor to oxygenate an organic compound, a reaction that depends on a reduced flavin cofactor to activate O 2 by electron donation. These enzymes are classified as external (EC 1.14.13) and internal monooxygenases (EC 1.13.12). WebMany flavoproteins catalyze the oxidation of primary and secondary amines, with the transfer of a hydride equivalent from a carbon-nitrogen bond to the flavin cofactor. Most of these amine oxidases can be classified into two structural families, the D-amino acid oxidase/sarcosine oxidase family and the monoamine oxidase family. kids toys 3 year old
