This domain family is found at the N-terminal end of Turret protein (TP), also known as VP3, from Reovirus. This GTase domain, responsible for the catalysis of the first step of RNA capping, consists of two subdomains, which form a deep and narrow cleft. This domain is rich in beta strands and adopts a pentameric assembly [1,2].	Domain
