dc.description.abstractAn aryl [beta]-hexosidase was purified 800-fold from bovine liver. The purified enzyme hydrolyzed p-nitrophenyl glycosylpyranoside derivatives of [beta]--galactose, [beta]--glucose, [beta]--xylose, [beta]--mannose, and [alpha]--arabinose, but did not hydrolyze several other p-nitrophenyl glycosides. The enzyme also catalyzed hydrolysis of a variety of plant arylglucosides. Disaccharides, polysaccharides, glycolipids, glycoproteins, and glycosaminoglycans containing terminal nonreducing [beta]--galactopyranosyl or [beta]--glucopyranosyl residues were not hydrolyzed. The pH optima for the several substrates tested ranged from 7.0 to 9.5. The purified enzyme was homogeneous by disc gel electrophoresis and had a molecular weight of 41,000 by Sephadex gel filtration and 46,000 by disc gel electrophoresis performed in the presence of sodium dodecyl sulfate. The enzyme readily transferred glycosyl residues from susceptible [beta]-galactosides or [beta]-glucosides to other sugars; the resulting products were not hydrolyzed by the enzyme. Methyl [alpha]--glucopyranoside was the most efficient carbohydrate acceptor compound tested. The enzyme exhibited a Km for p-nitrophenyl [beta]--galactopyranoside of 1.78 x 10-3 and for p-nitrophenyl [beta]--glucopyranoside, 2.50 x 10-3 when incubations were conducted in the presence of 0.15 methyl [alpha]--glucopyranoside. Aryl [beta]-hexosidase was found in the cytosol of all mammalian livers tested, but could not be detected in liver of birds, reptiles, or fish; low levels were detected in frog liver. Analysis of bovine extracts indicated that the enzyme occurred in liver, kidney, and intestinal mucosa; it was not detected in testis, spleen, serum, or muscle.en_US
