Pentalenene oxygenase

Pentalenene oxygenase (, Formerly, PtlI) is an enzyme with systematic name pentalenene,NADPH:oxygen 13-oxidoreductase. This enzyme catalyses the following chemical reaction


 * pentalenene + 2 NADPH + 2 H+ + 2 O2 $$\rightleftharpoons$$ pentalen-13-al + 2 NADP+ + 3 H2O (overall reaction)
 * (1a) pentalenene + NADPH + H+ + O2 $$\rightleftharpoons$$ pentalen-13-ol + NADP+ + H2O
 * (1b) pentalen-13-ol + NADPH + H+ + O2 $$\rightleftharpoons$$ pentalen-13-al + NADP+ + 2 H2O

Pentalenene oxygenase is a heme-thiolate protein (P-450).
