Enzyme Information

Heme oxygenase (biliverdin-IX-beta and delta-forming).
based on mapping to UniProt O69002
(1) Protoheme + 3 reduced acceptor + 3 O(2) = biliverdin-IX-delta + CO + Fe(2+) + 3 acceptor + 3 H(2)O. (2) Protoheme + 3 reduced acceptor + 3 O(2) = biliverdin-IX-beta + CO + Fe(2+) + 3 acceptor + 3 H(2)O.
-!- The enzyme, characterized from the bacterium Pseudomonas aeruginosa, differs from EC 1.14.15.20 in that the heme substrate is rotated by approximately 110 degrees within the active site, resulting in cleavage at a different part of the ring. -!- It forms a mixture of about 70% biliverdin-IX-delta and 30% biliverdin-IX-beta.
