Function

Lignostilbene-α,β-dioxygenase A (LsdA) is an enzyme found in the bacteria Sphingomonas paucimbilis.^[1] It is used to catalyze the substrate, lignostilbene, into two vanillin molecules. Vanillin is a member of the benzaldehydes class and plays a role in the plant metabolite^[2]. Lignin is found in the plant cell walls, lignocellulose, and it gives the plant its rigid structure. The depolymerization of the lignin can allow for better use of the plants resources as a source of biofuel.

Broader Implications

Lignocellulosic biomasses have been used for biofuels, mainly bio-ethanol. The abundant avaiability of the raw material make the use of biomasses ideal. With the rise of carbon emission, biomasses can be used to substitue the need for carbon based fuel, as long as, the biomass is carbon neutral.^[3]
