| 4.1.99.5 | octadecanal + O2 + 2 NADPH + 2 H+ = heptadecane + formate + H2O + 2 NADP+ | mechanistic proposal for the oxygen-independent formation of alkanes by the enzyme. In this mechanism the external reducing system functions catalytically to generate a reactive ketyl radical anion and facilitate carbon-carbon bond cleavage | Synechococcus sp. | |

| 4.1.99.5 | additional information | the enzyme catalyzes the unusual hydrolysis of aldehydes to produce alkanes and formate. The reaction requires an external reducing system but does not require oxygen. The enzyme catalyzes aldehyde decarbonylation at a much faster rate under anaerobic conditions, and the oxygen in formate derives from water. Eventhough an oxygen-dependent mechanism may operate in cAD, the oxygen-independent decarbonylation of aldehydes is a general feature of these enzymes | Synechococcus sp. | ? | - |
