DEXH-box helicase domain of type III restriction enzyme res subunit; Members of this model includes both type I and type III restriction enzymes. Both are hetero-oligomeric proteins. Type I REs are encoded by three closely linked genes: a specificity subunit (HsdS or S) for recognizing a DNA sequence, a methylation subunit (HsdM or M) for methylating the recognized target bases, and a restriction subunit (HsdR or R) for the translocation and random cleavage of non-methylated DNA. They show diverse catalytic activities, including methyltransferase (MTase), ATP hydrolase (ATPase), DNA translocation and restriction activities. These enzymes cut at a site that differs, and is a random distance (at least 1000 bp) away, from their recognition site. Cleavage at these random sites follows a process of DNA translocation, which shows that these enzymes are also molecular motors. The recognition site is asymmetrical and is composed of two specific portions: one containing 3-4 nucleotides, and another containing 4-5 nucleotides, separated by a non-specific spacer of about 6-8 nucleotides. Type III enzymes are composed of two subunits, Res and Mod. The Mod subunit recognizes the DNA sequence specific for the system and is a modification methyltransferase; as such, it is functionally equivalent to the M and S subunits of type I restriction endonucleases. Res is required for restriction, although it has no enzymatic activity on its own. Type III enzymes recognize short 5-6 bp-long asymmetric DNA sequences and cleave 25-27 bp downstream to leave short, single-stranded 5' protrusions. They require the presence of two inversely oriented unmethylated recognition sites for restriction to occur. These enzymes methylate only one strand of the DNA, at the N-6 position of adenosyl residues, so newly replicated DNA will have only one strand methylated, which is sufficient to protect against restriction. Both type I and type III REs are members of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

Helicase conserved C-terminal domain; The Prosite family is restricted to DEAD/H helicases, whereas this domain family is found in a wide variety of helicases and helicase related proteins. It may be that this is not an autonomously folding unit, but an integral part of the helicase.

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.

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:

(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
