Popis: The main product of DpTPS9 from the social amoeba Dictyostelium purpureum was identified as (4S,7R)-germacra-(1(10)E,5E)-dien-11-ol that is also known as an intermediate of bacterial geosmin synthase, but the experimentally verified cyclisation mechanisms differ. Together with the low sequence identity this points to convergent evolution. The functionality of selected residues in DpTPS9 was investigated via site-directed mutagenesis experiments.
