    Degradation of the plant cell wall requires the synergistic action of a consortium of predominantly modular enzymes. In Clostridiae, these biocatalysts are organized into a supramolecular assembly termed a "cellulosome." This multienzyme complex possesses, in addition to its well-described cellulolytic activity, an apparatus specific for xylan degradation. Cinnamic acid esterases hydrolyze the ferulate groups involved in the crosslinking of arabinoxylans to lignin and thus play a key role in the degradation of the plant cell wall in addition to having promising industrial and medical applications.
