Kajiura and Yoshizawa et al. identify three new prenyltransferases in the tree Eucommia ulmoides that synthesize exceptionally high molecular weight trans-1,4-polyisoprene (TPI). Through crystal structure and mutational analyses, they identify key residues required for TPI synthesis and reveal its functional importance in seed development.
