Protein

Cytosolic beta-glucosidase

Gene

Gba3

Organism
Cavia porcellus (Guinea pig)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Seems to be involved in the intestinal absorption and metabolism of dietary flavonoid glycosides. Able to hydrolyze a broad variety of glycosides including phytoestrogens, flavonols, flavones, flavanones and cyanogens. Possesses beta-glycosylceramidase activity and may be involved in a nonlysosomal catabolic pathway of glycosylceramide (By similarity).By similarity

Catalytic activityi

Hydrolysis of terminal, non-reducing beta-D-glucosyl residues with release of beta-D-glucose.

Enzyme regulationi

Inhibited by 2,4-dinitrophenyl-2-fluoro-2-deoxy-beta-D-glucopyranoside.1 Publication
