Automated methodology for monitoring the presence of one or more glycosidases in biological extracts has been described (l-7). These procedures require use of large amounts of synthetic glycoside(s) (l-4,6,7), compound automated systems (5), or extensive mechanical and/or electrical alterations of existing apparatus (8). The present paper describes a simple modification of the Technicon Basic A...

Specific activities of seven acid glycosidases: beta-hexosaminidase, alpha- and beta-galactosidase, alpha- and beta-mannosidase, alpha-glucosidase and alpha-fucosidase were determined in various parts of the domestic hen oviduct (infundibulum, isthmus, shell gland and vagina). The activity of most enzymes was the highest in the isthmus. Multiple forms of all acid glycosidases from the isthmus w...

Glycosidases are very important enzymes involved in a variety of biochemical processes with a special importance to biotechnology, food industry, and pharmacology. Novel structurally simple inhibitors derived from cyclohexane-1,2-dicarboxylic acids were synthesized and tested against several fungal glycosidases from Aspergillus oryzae and Penicilliumcanescens. The presence of at least two carbo...

BACKGROUND Factors that prevent colonic mucosal invasion by pathogenic Entamoeba histolytica are not understood. A key initial step in pathogenesis of injury induced by amoeba is adherence to target cells mediated by a surface glycoprotein lectin on E histolytica. Mucin degrading bacteria normally present in the colon lumen produce glycosidases that degrade soluble or cell surface glycoconjugat...
