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

Cytoplasmic polyhedrosis virus (CPV) has a turreted single-layer capsid consisting of 12 pentameric turrets on the five-fold vertices. Each turret has one Turret protein (TP), also known as VP3, which shows a polyhedrin-binding domain (PBD), a guanylyltransferase (GTase) domain (Pfam:PF20790), two methylase domains and a bridge domain (this entry), which has two discontinuous regions [1,2].

Cytoplasmic polyhedrosis virus (CPV) has a turreted single-layer capsid consisting of 12 pentameric turrets on the five-fold vertices. Each turret has one Turret protein (TP), also known as VP3, which shows a polyhedrin-binding domain (PBD), a guanylyltransferase (GTase) domain (Pfam:PF20790), two methyltransferase domains and a bridge domain. This entry represents the second methyltransferase domain, which is found at the C-terminal end of the protein [1,2].	Domain

Cytoplasmic polyhedrosis virus (CPV) has a turreted single-layer capsid consisting of 12 pentameric turrets on the five-fold vertices. Each turret has one Turret protein (TP), also known as VP3, which shows a polyhedrin-binding domain (PBD), a guanylyltransferase (GTase) domain (Pfam:PF20790), two methyltransferase domains and a bridge domain. This entry represents the first methyltransferase domain (MTase-1), which has the small brace domain inserted on it [1,2].	Domain

This domain is found in Capsid shell protein VP1 from Cytoplasmic polyhedrosis virus (CPV). VP1, one of the three major capsid proteins of CPV, has an overall thin-plate-like shape similar to its counterparts in other reoviruses except for a protrusion domain on the outer capsid surface, which is unique in single-layered cypoviruses [1].	Domain

This entry includes capsid proteins from cypoviruses which form the icosahedral capsid through self-assembly (they are also known as inner layer core proteins). The capsid encapsulates and protects the genomic RNA. These viruses encode VP1, VP3 and VP5 as major capsid proteins, encoded by RNA segment 1 and 3 in the case of VP1 and VP3, respectively, whereas RNA segment encoding VP5 is still unclear. This entry represents the C-terminal domain of capsid proteins from cypovirusus [1-3].	Domain
