FunFam 10224: Heme-degrading monooxygenase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Heme oxygenase (biliverdin-producing). [EC: 1.14.14.18]
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.
