Acyl-Lipid Δ⁶-Desaturase May Act as a First FAD in Cyanobacteria

Biomolecules, 2022
Fatty acid desaturases (FADs) play important roles in various metabolic and adaptive pathways in all living organisms. They represent a superfamily of oxygenases that introduce double bonds into the acyl chains of fatty acids (FAs).
