Cellulosomes are complexes of cellulolytic enzymes created by bacteria such as Clostridium and Bacteroides. They consist of catalytic subunits such as glycoside hydrolases, polysaccharide lyases and carboxyl esterases bound together by scaffoldins consisting of cohesins connected to other functional units such as the enzymes and carbohydrate binding modules via dockerins. They assist in digestion or degradation of plant cell wall materials, most notably cellulose.
For further details see the description on the specialist carbohydrate active enzyme wiki resource CAZypedia under cellulosome.
