Identification
NameGlucan 1,3-beta-glucosidase I/II
Synonyms
  • Exo-1,3-beta-glucanase I/II
  • Soluble cell wall protein 6
Gene NameEXG1
Enzyme Class
Biological Properties
General FunctionInvolved in hydrolase activity, hydrolyzing O-glycosyl compounds
Specific FunctionGlucanases possibly play a role in cell expansion during growth, in cell-cell fusion during mating, and in spore release during sporulation. This enzyme hydrolyzes both 1,3-beta- and 1,6- beta-linkages and even has beta-glucosidase activity. It could also function biosynthetically as a transglycosylase
Cellular LocationSecreted, cell wall. Secreted
