Acid hydrolases in blister fluid. II. Characterization and quantification of glycoside hydrolases.
Seven glycoside hydrolases have been investigated in suction blister fluid, interstitial fluid and in serum. Six of these have been characterized; no differences could be demonstrated between the corresponding enzymes from the various sources. The remaining enzyme (beta-glucosidase) was not found. Quantitative data suggest that 2 enzymes (beta-acetylglucosaminidase and beta-glucuronidase) diffuse freely from the epidermis into blister fluid, whereas 4 (alpha-glucosidase, alpha- and beta-galactosidase and alpha-mannosidase) are almost entirely retained in the roof of the bulla.
