Enzyme Information
| 1.14.14.18 |
Heme oxygenase (biliverdin-producing).
based on mapping to UniProt P06762
Protoheme + 3 [reduced NADPH--hemoprotein reductase] + 3 O(2) = biliverdin + Fe(2+) + CO + 3 [oxidized NADPH--hemoprotein reductase] + 3 H(2)O.
-!- This mammalian enzyme participates in the degradation of heme. -!- The terminal oxygen atoms that are incorporated into the carbonyl groups of pyrrole rings A and B of biliverdin are derived from two separate oxygen molecules. -!- The third oxygen molecule provides the oxygen atom that converts the alpha-carbon to CO. -!- The enzyme requires NAD(P)H and EC 1.6.2.4. -!- Cf. EC 1.14.15.20. -!- Formerly EC 1.14.99.3.
