Function
UDB17_HUMAN UDP-glucuronosyltransferase (UGT) that catalyzes phase II biotransformation reactions in which lipophilic substrates are conjugated with glucuronic acid to increase the metabolite's water solubility, thereby facilitating excretion into either the urine or bile (PubMed:8798464, PubMed:16595710, PubMed:18719240, PubMed:19022937, PubMed:23288867). Catalyzes the glucuronidation of endogenous steroid hormones such as androgens (epitestosterone, androsterone) and estrogens (estradiol, epiestradiol) (PubMed:8798464, PubMed:16595710, PubMed:18719240, PubMed:19022937, PubMed:23288867).[1] [2] [3] [4] [5]
