Uricase is mainly located in the liver where it forms an elctron dense crystalline core in peroxisomes. It is a tetramer of identical subunits each containing copper binding sites. X-ray crystallography shows that uric acid binds to the active site as a monoanion and is deprotonated as a dianion which is then stabilized by Arg 176 and Gln 228. Uricase can be inhibited by both cyanide and chloride ions. Oxonate competitively inhibits uricase. | Uricase is mainly located in the liver where it forms an elctron dense crystalline core in peroxisomes.
