Background and Objective: Uricase (EC 1.7.3.3) is an enzyme which catalyses uric acid to H2O2 and alantoin and is utilized in the treatment of hyperuricemia or gout. The aim of this study was cloning of Aspergillus flavus uricase synthetic gene into pET-28(a) and its recombinant expression in E. coli Materials and Methods: The coding sequence of uricase retrieved from gene bank and once opti...

Background and Aims: Rotavirus enteritis is an acute viral infectious disease among infants. VP7 protein has a key role in attachment and entry virus into the target cell. The VP7 protein is involved in inducing the production of neutralizing antibodies that protect infants against reinfection of the virus. The aim of this study was to heterologous expression of the VP7 gene of bovine rotavirus...
