Proline cis-trans-isomerization is a regulatory mechanism in many biological processes. The slow isomerization transition is catalyzed by isomerases, a ubiquitous class of enzymes. To study the enzymatic isomerization on single molecule level, a high-resolution optical trap was built in the frame of this work. Using a novel fast-force jump protocol, SlyD catalyzed isomerization in filamin A domain 20 was investigated. Thereby, the kinetic network of domain 20 was fully characterized in the presence of an isomerase for the first time.
