1. The Bach1-sMaf heterodimer regulates the heme oxygenase -1 gene. 2. NovR is a non-heme iron oxygenase with a unique bifunctional catalysis. 3. HMOX1 and HMOX2 ( this enzyme ) belong to the heme oxygenase family. 4. Sickle hemoglobin induces the expression of heme oxygenase -1 in hematopoietic cells. 5. Heme oxygenase activity is induced by its substrate heme and by various nonheme substances. 6. It also decreases cyclo-oxygenase activity. 7. The interdomain linker between the oxygenase and reductase domains contains a calmodulin-binding sequence. 8. Gene disruption studies indicate a cytochrome P450 oxygenase as the enzyme that performs the coupling reactions. 9. Another reaction of 2, 6-dihydroxypyridine highlights its function as a substrate for oxygenase . 10. PDB structure 3rub : the ribulose-1, 5-bisphosphate carboxylase / oxygenase from tobacco.
