DE   heme oxygenase (biliverdin-IX-beta and delta-forming).
CA   (1) 3 AH2 + 3 H(+) + heme b + 3 O2 = 3 A + biliverdin IXdelta + CO +
CA   Fe(2+) + 3 H2O.
CA   (2) 3 AH2 + 2 H(+) + heme b + 3 O2 = 3 A + biliverdin IXbeta + CO +
CA   Fe(2+) + 3 H2O.
CC   -!- The enzyme, characterized from the bacterium Pseudomonas aeruginosa,
CC       differs from EC 1.14.15.20 in that the heme substrate is rotated by
CC       approximately 110 degrees within the active site, resulting in
CC       cleavage at a different part of the ring.
CC   -!- It forms a mixture of about 70% biliverdin-IX-delta and 30%
CC       biliverdin-IX-beta.
