Uricase (EC 1.7.3.3, UC) catalyzes the oxidation of uric acid (UA) to more soluble allantoin thereby lowering plasma UA levels. In humans, when concentration of UA exceeds >7mg/dl, it leads to hyperuricemia, gout, nephrolithiasis and urolithiasis. A new remedy to cure such metabolic diseases is the enzyme supplementation therapy by UC but with high degree of antigenic independence. Therefore screening of new uricase sources to expand its usefulness and reduced antigenecity is needed. Present study employed cheminformatics approach to construct models of reported UC from different sources viz. Bacillus megaterium, Streptomyces bingchenggensis BCW-1, Paenibacillus sp, Solibacter usitatus Ellin6076, Truepera radiovictrix DSM 17093 and Ktedonobacter racemifer DSM 4496 in order to study their structure-function relationship for enzyme mass production and modification for improved characteristics. BioMed CAChe version 6.1 was further used to study enzyme-substrate interactions of models with uric acid using docking approach. Results indicated that models for UC of Streptomyces bingchenggensis BCW-1 accounted for better regio-specificity towards UA, supporting the interested metabolism and thus may further be implicated in enzyme supplementation therapy for hyperuricemic associated disorders.
