Namealkane biosynthesis, cyanobacterial
DescriptionThis two gene system converts even-numbered saturated and unsaturated fatty acids (largely C16 and C18) into n-1 odd-numbered alkanes or alkenes [1]. The most commonly observed alkanes in cyanobacteria, where this system is found, are heptadecane, pentadecane and methyl-heptadecane [1]. Fatty acyl-acyl carrier protein (ACP) substrates are first converted to fatty aldehydes by the action of an NAD(P)H-dependent Acyl-ACP reductase. This reductase is distantly related to the short-chain dehydrogenase or reductase (SDR) family (PF00106). The fatty aldehyde is subsequently converted to hydrocarbons by an aldehyde decarbonylase, releasing CO. This decarbonylase is distantly related to a family of di-iron-containing reductases including ribonucleotide reductase.
