Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A biohybrid ring‐opening olefin metathesis polymerization catalyst based on the reengineered β‐barrel protein FhuA ΔCVF^tev was chemically modified with respect to the covalently anchored Grubbs–Hoveyda type catalyst. Shortening of the spacer (1, 3‐propanediyl to methylene) between the N‐heterocyclic carbene ligand and the cysteine site 545 increased the ROMP activity toward a water‐soluble 7‐oxanorbornene derivative. The <italic>cis</italic>/<italic>trans</italic> ratio of the double bond in the polymer was influenced by the hybrid catalyst.</p> </abstract>
