KEGG   ENZYME: 1.14.14.18
Entry
EC 1.14.14.18               Enzyme                                 
Name
heme oxygenase (biliverdin-producing);
ORP33 proteins;
haem oxygenase (ambiguous);
heme oxygenase (decyclizing) (ambiguous);
heme oxidase (ambiguous);
haem oxidase (ambiguous);
heme oxygenase (ambiguous);
heme,hydrogen-donor:oxygen oxidoreductase (alpha-methene-oxidizing, hydroxylating)
Class
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen into the other donor
Sysname
protoheme,NADPH---hemoprotein reductase:oxygen oxidoreductase (alpha-methene-oxidizing, hydroxylating)
Reaction(IUBMB)
protoheme + 3 [reduced NADPH---hemoprotein reductase] + 3 O2 = biliverdin + Fe2+ + CO + 3 [oxidized NADPH---hemoprotein reductase] + 3 H2O [RN:R00311]
Reaction(KEGG)
R00311
Substrate
protoheme [CPD:C00032];
[reduced NADPH---hemoprotein reductase] [CPD:C03024];
O2 [CPD:C00007]
Product
biliverdin [CPD:C00500];
Fe2+ [CPD:C14818];
CO [CPD:C00237];
[oxidized NADPH---hemoprotein reductase] [CPD:C03161];
H2O [CPD:C00001]
Comment
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 [4]. 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, NADPH---hemoprotein reductase. cf. EC 1.14.15.20, heme oxygenase (biliverdin-producing, ferredoxin).
History
