ENZYME entry: EC 1.14.99.58

Accepted Name
heme oxygenase (biliverdin-IX-beta and delta-forming)
Reaction catalysed
  • 3 AH2 + 3 H(+) + heme b + 3 O2 <=> 3 A + biliverdin IXdelta + CO + Fe(2+) + 3 H2O
  • 3 AH2 + 2 H(+) + heme b + 3 O2 <=> 3 A + biliverdin IXbeta + CO + Fe(2+) + 3 H2O
Comment(s)
  • 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.
