Cohesin-Dockerin interactions are at the core of cellulosomal assembly and organization. They are highly specific and form stable complexes, allowing cellulosomes to adopt distinct conformations. Each cellulosomal system seems to have a particular organizational strategy that can vary in complexity according to the nature of its Cohesin-Dockerin interactions.

Cohesins and dockerins are complementary interacting protein modules that form stable and highly specific receptor-ligand complexes. They play a crucial role in the assembly of cellulose-degrading multi-enzyme complexes called cellulosomes and have potential applicability in several technology areas, including biomass conversion processes. Here, we describe several exceptional properties of cohesin-dockerin complexes, including their tenacious biochemical affinity, remarkably high mechanostability and a dual-binding mode of recognition that is contrary to the conventional lock-and-key model of receptor-ligand interactions.
