== Function ==
 +
[https://www.uniprot.org/uniprot/EXG1_CANAL EXG1_CANAL] 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.<ref>PMID:21713010</ref> <ref>PMID:22876186</ref>

In some species of Candida the CUG codon is encoded as serine and not leucine. In the case of the exo-beta-1,3-glucanase from the pathogenic fungus C. albicans there are two such translational events, one in the prepro-leader sequence and the other at residue 64. Overexpression of active mature enzyme in a yeast host indicated that these two positions are tolerant to substitution. By comparing the crystal structure of the recombinant protein with that of the native (presented here), it is seen how either serine or leucine can be accommodated at position 64. Examination of the relatively few solved protein structures from C. albicans indicates that other CUG encoded serines are also found at non-essential surface sites. However such codon usage is rare in C. albicans, in contrast to C. rugosa, with direct implications for respective recombinant protein production.
