| Enzyme Function | FUNCTION: Major glucan 1,3-beta-glucosidase required for cell wall integrity. Beta-glucanases participate in the metabolism of beta-glucan, the main structural component of the cell wall. Can also function biosynthetically as a transglycosylase. Functions to deliver glucan from the cell to the extracellular matrix. Does not appear to impact cell wall glucan content of biofilm cells, nor is it necessary for filamentation or biofilm formation. Involved in cell-substrate and cell-cell adhesion. Adhesion to host-cell surfaces is the first critical step during mucosal infection. XOG1 is target of human antimicrobial peptide LL-37 for inhibition of cell adhesion. {ECO:0000269|PubMed:21713010, ECO:0000269|PubMed:22876186}. |
