This family of glycoside hydrolases was recently discovered characterising a new β-glucosidase from the hyperthermophilic archaeon Sulfolobus solfataricus [1]. This enzyme is distantly related to the human non-lysosomal bile acid b-glucosidase GBA2, also known as glucocerebrosidase. GH116 contains acid β-glucosidase (EC 3.2.1.45), β-glucosidase (EC 3.2.1.21) and β-xylosidase (EC 3.2.1.37) from the three domains of life.
