WebMar 19, 2024 · CylC and CylK are important for the dimerization of the final ketide chain in the biosynthesis of (7.7)paracyclophane to form the characteristic cyclic structure. The absence of these two genes in the MKS cluster suggests that it does not produce a dimeric, cyclic structure-like (7.7)paracyclophane, but perhaps a linear analogue.
