Benzylideneacetone (BZA) is a metabolite of gram-negative entomopathogenic bacterium Xenorhabdus nematophila, and it acts as an enzyme inhibitor against phospholipase A2 (PLA2). PLA2 catalyzes a committed biosynthetic step of eicosanoids, which mediate insect immune reactions to infection by microbial pathogens.

Benzalacetone synthase (BAS) from Rheum palmatum is a plant-specific type III polyketide synthase that catalyzes the one-step decarboxylative condensation of 4-coumaroyl-CoA with malonyl-CoA to produce the diketide 4-(4-hydroxyphenyl)-but-3-en-2-one. Recombinant BAS expressed in Escherichia coli was crystallized by the sitting-drop vapour-diffusion
