IntEnz Enzyme Nomenclature


Accepted name:
albendazole monooxygenase (sufoxide-forming)
Other names:
albendazole sulfoxidase [ambiguous]
albendazole hydroxylase [ambiguous]
Systematic name:
albendazole,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (sufoxide-forming)



This is one of the activities carried out by some microsomal cytochrome P450 monooxygenases. A similar conversion is also carried out by a different microsomal enzyme (EC, albendazole monooxygenase (flavin-containing)), but it is estimated that cytochrome P450s are responsible for 70% of the activity.
