Neutral cytosolic beta-glycosidase with a broad substrate specificity that could play a role in the catabolism of glycosylceramides (Probable). Has a significant glucosylceramidase activity in vitro. However, that activity is relatively low and its significance in vivo is not clear (By similarity). Hydrolyzes galactosylceramide/GalCer, glucosylsphingosine/GlcSph and galactosylsphingosine/GalSph. However, the in vivo relevance of these activities is unclear (By similarity). 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 (Probable). 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 (By similarity). Could also play a role in the catabolism of cytosolic sialyl free N-glycans (By similarity). Hydrolysis of terminal, non-reducing beta-D-glucosyl residues with release of beta-D-glucose. a beta-D-glucosyl-(1<->1')-N-acylsphing-4-enine + H2O = an N-acylsphing-4-enine + D-glucose a beta-D-galactosyl-(1<->1')-N-acylsphing-4-enine + H2O = an N-acylsphing-4-enine + D-galactose beta-D-glucosyl-(1<->1)-sphing-4-enine + H2O = D-glucose + sphing-4-enine beta-D-glucosyl-(1<->1)-N-octadecanoylsphing-4-enine + H2O = D-glucose + N-octadecanoylsphing-4-enine beta-D-galactosyl-(1<->1)-sphing-4-enine + H2O = D-galactose + sphing-4-enine beta-D-galactosyl-(1<->1')-N-octadecanoylsphing-4-enine + H2O = D-galactose + N-octadecanoylsphing-4-enine a beta-D-xylosyl-(1<->1')-N-acylsphing-4-enine + cholesterol = an N-acylsphing-4-enine + cholesteryl 3-beta-D-xyloside Inhibited by 2,4-dinitrophenyl-2-fluoro-2-deoxy-beta-D-glucopyranoside. Present in hepatocytes (at protein level). The N-terminus is blocked. Belongs to the glycosyl hydrolase 1 family. Klotho subfamily.
