• demonstrate the importance of the right choice of the membrane protein stabilizer for biohybrid catalysis. Results and Discussion For solubilizing the transmembrane protein FhuA ΔCVFtev PE–PEG and MPD were applied as stabilizing agent and phenylacetylene polymerization was performed as model reaction (Figure
