IUBMB Comments

protoheme,donor:oxygen oxidoreductase (biliverdin-IX-beta and delta-forming)

The enzyme, characterized from the bacterium Pseudomonas aeruginosa, differs from EC 1.14.15.20, heme oxygenase (biliverdin-producing, ferredoxin), 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.
