- Aldehyde deformylating oxygenases (ADO) (EC 4.1.99.5) are a family of enzymes which catalyze the oxygenation of medium and long chain aldehydes to alkanes via the removal of a carbonyl group as formate. n-aldehyde + O2 + 2 NADPH + H+ → (n-1)-alkane + formate + H2O + 2 NADP+ Aldehyde deformylating oxygenases are found in cyanobacteria as part of the alkane biosynthesis pathway. Their substrates are medium- to long-chain aldehydes formed from acyl-ACP by acyl-ACP reductases (EC 1.2.1.80), commonly of 16 and 18 carbons, but potentially as short as nonanal and decanal. Compared to other aldehyde decarbonylases, such as insect or plant aldehyde decarbonylase, cyanobacterial ADO is unusual in evolving formate rather than CO or CO2 and for residing in the cytosol. It is also enzymatically unusual in catalyzing an formally hydrolytic and redox-neutral oxygenation of the substrate. (en)
