Three-dimensional structure of isoprene synthase and its use thereof for generating variants

摘要

The present invention provides a three-dimensional structures of P. tremuloides isoprene synthase and P. alba isoprene synthase. The invention also provides methods of using the three-dimensional structure to design isoprene synthases with improved activity for increased isoprene production in microbial host cells. Biosynthetically produced isoprene of the present invention finds use in the manufacture of rubber and elastomers.
