EC 1.14.15.32     
Accepted name: pentalenene oxygenase
Reaction: pentalenene + 4 reduced ferredoxin [iron-sulfur] cluster + 4 H+ + 2 O2 = pentalen-13-al + 4 oxidized ferredoxin [iron-sulfur] cluster + 3 H2O (overall reaction)
(1a) pentalenene + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H+ + O2 = pentalen-13-ol + 2 oxidized ferredoxin [iron-sulfur] cluster + H2O
(1b) pentalen-13-ol + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H+ + O2 = pentalen-13-al + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H2O
