Papillomavirus helicase; This is the C-terminal ATPase/helicase domain 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 pfam00508. The domain architecture of E1 is similar to that of the SV40 T-antigen.

The AAA+ (ATPases Associated with a wide variety of cellular Activities) superfamily represents an ancient group of ATPases belonging to the ASCE (for additional strand, catalytic E) division of the P-loop NTPase fold. The ASCE division also includes ABC, RecA-like, VirD4-like, PilT-like, and SF1/2 helicases. Members of the AAA+ ATPases function as molecular chaperons, ATPase subunits of proteases, helicases, or nucleic-acid stimulated ATPases. The AAA+ proteins contain several distinct features in addition to the conserved alpha-beta-alpha core domain structure and the Walker A and B motifs of the P-loop NTPases.

Papillomavirus E1, DNA-binding domain; 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 pfam00508 at the origin of replication (ori). 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. 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. E1 has a domain architecture and function similar to SV40 T-antigen.

Parvovirus non-structural protein NS1; This family also contains the NS2 protein. Parvoviruses encode two non-structural proteins, NS1 and NS2. The mRNA for NS2 contains the coding sequence for the first 87 amino acids of NS1, then by an alternative splicing mechanism mRNA from a different reading frame, encoding the last 78 amino acids, makes up the full length of the NS2 mRNA. NS1, is the major non-structural protein. It is essential for DNA replication. It is an 83-kDa nuclear phosphoprotein. It has DNA helicase and ATPase activity.

of the residues that compose this conserved feature have been mapped to the query sequence.
Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.
To view your query sequence embedded in that multiple sequence alignment, click on the colored bars in the Graphical Summary portion of the search results page,
or click on the triangles, if present, that represent functional sites (conserved features)
mapped to the query sequence.
Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.
(labeled illustration) Standard Display shows only the best scoring domain model from each source, in each hit category listed below for each region on the query sequence.
(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
the domain superfamily to which the specific and non-specific hits belong
multi-domain models that were computationally detected and are likely to contain multiple single domains
