UniProtKB description: Catalyzes the decarboxylation of free fatty acids to n-alkanes or n-alkenes in response to blue light (PubMed:28860382, PubMed:30106504, PubMed:30673222). Substrate preference is toward fatty acids with C16 or C17 chains (PubMed:28860382, PubMed:30106504, PubMed:30673222). Converts n-octanoic acid (C8 chain) more efficiently than palmitate (n-hexadecanoic acid, C16 chain) into n-heptane (C7 chain) and n-pentadecane (C15 chain), respectively, partly due to an autocatalytic effect of its n-heptane product (PubMed:37000872). Saturated fatty acids are converted to alkanes, not alkenes (PubMed:28860382). The decarboxylation is initiated through electron abstraction from the fatty acid by the photo-excited FAD (PubMed:28860382).
