Cellulosome anchoring protein, cohesin domain (IPR002102)

Short name: Cohesin_dom

Overlapping homologous superfamilies

Domain relationships



Cohesin domains interact with a complementary domain, termed the dockerin domain (see IPR002105). The cohesin-dockerin interaction is the crucial interaction for complex formation in the cellulosome [PMID: 9083107].

The scaffoldin component of the cellulolytic bacterium Clostridium thermocellum is a non-hydrolytic protein which organises the hydrolytic enzymes in a large complex, called the cellulosome. Scaffoldin comprises a series of functional domains, amongst which is a single cellulose-binding domain and nine cohesin domains which are responsible for integrating the individual enzymatic subunits into the complex.
