β-glucuronidase

GUSB

β-glucuronidase is a glycoside hydrolase widely distributed in mammalian tissues, body fluids, microbiota, plants, fish, insects and mollusks. β-glucuronidase belongs to GH family 1, 2, 30, 79, 154 and GH-A. β-glucuronidase can hydrolyze estrogen glucuronides, regulate the enterohepatic circulation and reabsorption of estrogen, and affect estrogen metabolism. β-glucuronidase can also hydrolyze the extracellular sugar residues on the TRPV5 channel, trapping it in the plasma membrane, maintaining calcium channel activity and membrane calcium permeability. This target is related to many disease areas. For example, in cancer, its increased activity is related to the occurrence and development of colorectal cancer, breast cancer, ovarian cancer, etc.; in metabolic diseases, it is related to diabetes and its induced periodontitis; in inflammatory diseases, it involves bacterial peritonitis, bacterial meningitis, pelvic inflammatory disease, etc.; in addition, it is also related to diseases such as endometriosis^[1]^[2]^[3]^[4]^[5]^[6]^[7].
