[Immunological demonstration of beta-glucuronidase in eccrine sweat (author's transl)].

Electrophoretic and immunological investigations on highly concentrated sweat have shown that human eccrine sweat contains 6 different esterases. Two of them were found to hydrolyze naphthol-AS-Bi-beta-D-glucuronide. One of the two glucuronic acid ester splitting enzymes is likely to be a substrate-specific beta-glucuronidase. The other one is a non-specific carboxyl-esterase occurring in numerous organs and glandular secretions. This non-specific enzyme of widespread distribution can be mistaken for beta-glucuronidase because it hydrolyzes glucuronic acid esters as well as other synthetic substrates.
