UnderstandingtheRoleofOxygenasesinBiologicalProcesses

Oxygenasesareenzymesthatplayacrucialroleinmanybiologicalprocesses.Theyareinvolvedintheoxidationofawiderangeoforganiccompoundsthatcontaincarbon-carbondoublebonds,aromaticcompounds,aswellasothertypesofchemicalfunctionalgroups.Inthisarticle,wewilldiscussthedifferenttypesofoxygenases,theirfunctions,andtheimpacttheyhaveonourenvironment.

TheDifferentTypesofOxygenases

Therearetwomajortypesofoxygenases-monooxygenasesanddioxygenases.Monooxygenasesareenzymesthatinsertoneoxygenatomintothemoleculetheyareoxidizing,whiledioxygenasesincorporatebothatomsofamoleculeofmolecularoxygenintothesubstrate.Additionally,thereareseveralsubclassesofoxygenases,includingflavin-containingmonooxygenases(FMOs),cytochromeP450monooxygenases,andheme-containingdioxygenases.

TheFunctionsofOxygenases
