Multiple alignment of deduced amino acid sequences of transprenyl diphosphate synthases from L. erythrorhizon and other plant species. The FARM, conserved among all prenyl diphosphate synthases, is boxed. The target site of point mutation is highlighted in gray. The GenBank accession numbers are shown for each enzyme. The first two letters indicate the scientific names of each species: Ag, Abies grandis; Am, Antirrhinum majus; Mp, Mentha × piperita; Pa, Picea abies; Sl, Solanum lycopersicum; Zm, Zea mays.
