[[Heme oxygenase]], an essential enzyme in [[heme]] catabolism, cleaves heme to form [[biliverdin]], which is subsequently converted to bilirubin by [[biliverdin reductase]], and [[carbon monoxide]], a putative neurotransmitter. Heme oxygenase activity is induced by its substrate heme and by various nonheme substances. Heme oxygenase occurs as 2 [[isozyme]]s, an inducible heme oxygenase-1 and a constitutive heme oxygenase-2. [[HMOX1]] and HMOX2 (this enzyme) belong to the heme oxygenase family.<ref name="entrez">{{cite web | title = Entrez Gene: HMOX2 heme oxygenase (decycling) 2| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=3163| accessdate = }}</ref> | |||

Heme oxygenase 2 is an enzyme that in humans is encoded by the HMOX2 gene.[1][2]
Function
Heme oxygenase, an essential enzyme in heme catabolism, cleaves heme to form biliverdin, which is subsequently converted to bilirubin by biliverdin reductase, and carbon monoxide, a putative neurotransmitter. Heme oxygenase activity is induced by its substrate heme and by various nonheme substances. Heme oxygenase occurs as 2 isozymes, an inducible heme oxygenase-1 and a constitutive heme oxygenase-2. HMOX1 and HMOX2 (this enzyme) belong to the heme oxygenase family.[2]
