    Herein, we report the biosynthesis of protein heterocatenanes via a programmed sequence of multiple post-translational processing events including intramolecular chain entanglement, in situ backbone cleavage, and spontaneous cyclization. The approach is general, autonomous, and can obviate the need of any additional enzymes. The catenane topology was convincingly proven via combined techniques of SDS-PAGE, LC-MS, SEC, controlled proteolytic digestion, and protein crystallography. The crystal structure clearly shows two mechanically interlocked protein rings with intact folded domains. It opens new avenues to the nascent field of protein topology engineering.
