Mountain pine beetle (Dendroctonus ponderosae) CYP4Gs convert long and short chain alcohols and aldehydes to hydrocarbons

Hydrocarbon biosynthesis in insects involves the elongation of fatty acyl-CoAs to very-long chain fatty acyl-CoAs that are then reduced and converted to hydrocarbon, with the last step involving the oxidative decarbonylation of an aldehyde to hydrocarbon and carbon dioxide. Cytochromes P450 in the 4G family decarbonylate aldehydes to hydrocarbon. All insect acyl-CoA reductases studied to date reduce fatty acyl-CoAs to alcohols. The results of...
