synthesis | production of functionalized oligo-isoprenoids by enzymatic cleavage of rubber. A method for the preparation of reactive oligo-isoprenoids that can be used to convert polyisoprene latex or rubber waste materials into value-added molecules, biofuels, polyurethanes or other polymers. Emulsions of polyisoprene (latex) are treated with RoxAXsp, RoxBXsp, LcpK30 or with combinations of the three proteins. The cleavage products are purified by solvent extraction and FPLC separation. All products have the same general structure with terminal functions (CHO-CH2- and -CH2-COCH3) but differ in the number of intact isoprene units in between | Streptomyces sp. K30 |
