This is the DNA-binding domain (DBD) of Papillomavirus E1 protein, a DNA helicase that is required for initiation of viral DNA replication. This protein forms a complex with the E2 protein Pfam:PF00508 at the origin of replication (ori) [1,2]. This domain is found in the central region of E1 and binds DNA at specific sites of viral origin, and also binds cooperatively with E2-DBD. This domain comprises a five-stranded antiparallel beta-sheet flanked by alpha helices on each side [2]. This domain binds originally as a dimer in which each monomer binds to one half-site of the palindromic E1 binding site, and promotes the assembly of the hexameric helicase on the ori [2]. E1 has a domain architecture and function similar to SV40 T-antigen [1].	Domain
