Definition: Cervellases are a family of proteins that play a crucial role in several cellular processes. These proteins have been identified in various organisms, including plants, fungi, and bacteria. In plant cells, they are involved in the synthesis of cellulose, a type of polymer composed of glucose molecules. They also contribute to the breakdown of lignin, another polymer found in wood and other plant tissues. In fungi, they play a role in the process of cell wall formation, where they help form the
