Beta-glucoronidase is a lysosomal enzyme catylysing the decomposition of beta-D-glucoronides-compounds arising as a result of the combination of beta-D-glucoronic acid and a number of compounds both exo- and endogenous, containing hydroxylic, carboxylic, amine, imine or thiol groups. Beta-glucuronidase (betaGLU)-a lysosomal acid hydrolase responsible for the catalytic deconjugation of beta-D-glucuronides has emerged as a viable molecular target for several therapeutic applications. The enzymes activity level in body fluids is also deemed a potential biomarker for the diagnosis of some pathological conditions. The activity of beta-glucoronidase increases in many pathological conditions: liver infammations, cirrhosis of the liver, inflammations of other organs, cholestatic jaundice, tuberculosis, sarcoidosis and also in neoplasms. And many authors point to beta-glucoronidase as a sensitive indicator signalling cell damage.
