Cytosolic beta-glucosidase

Neutral cytosolic beta-glycosidase with a broad substrate specificity that could play a role in the catabolism of glycosylceramides. Has a significant glucosylceramidase activity in vitro. However, that activity is relatively low and its significance in vivo is not clear. Hydrolyzes galactosylceramides/GalCers, glucosylsphingosines/GlcSphs and galactosylsphingosines/GalSphs. However, the in vivo relevance of these activities is unclear. It can also hydrolyze a broad variety of dietary glycosides including phytoestrogens, flavonols, flavones, flavanones and cyanogens in vitro and could therefore play a role in the metabolism of xenobiotics. Possesses transxylosylase activity in vitro using xylosylated ceramides/XylCers (such as beta-D-xylosyl-(1<->1')-N-acylsphing-4-enine) as xylosyl donors and cholesterol as acceptor. Could also play a role in the catabolism of cytosolic sialyl free N-glycans.
