YhaM_OBF_like: A subfamily of OB folds similar to that found in Bacillus subtilis YhaM and Staphylococcus aureus cmp-binding factor-1 (SaCBF1). Both these proteins are 3'-to-5'exoribonucleases. YhaM requires Mn2+ or Co2+ for activity and is inactive in the presence of Mg2+. YhaM also has a Mn2+ dependent 3'-to-5'single-stranded DNA exonuclease activity. SaCBF is also a double-stranded DNA binding protein, binding specifically to cmp, the replication enhancer found in S. aureus plasmid pT181. Proteins in this group combine an N-terminal OB fold with a C-terminal HD domain. The HD domain is found in metal-dependent phosphohydrolases.

CRISPR-associated endonuclease Cas3-HD; CRISPR/Cas systems are widespread, mobile systems for host defense against invasive elements such as phage. In these systems, Cas3 designates one of the core proteins shared widely by multiple types of CRISPR/Cas system. This model represents an HD-like endonuclease that occurs either separately or as the N-terminal region of Cas3, the helicase-containing CRISPR-associated protein.

OB-fold nucleic acid binding domain; This family contains OB-fold domains that bind to nucleic acids. The family includes the anti-codon binding domain of lysyl, aspartyl, and asparaginyl -tRNA synthetases (See pfam00152). Aminoacyl-tRNA synthetases catalyze the addition of an amino acid to the appropriate tRNA molecule EC:6.1.1.-. This family also includes part of RecG helicase involved in DNA repair. Replication factor A is a hetero-trimeric complex, that contains a subunit in this family. This domain is also found at the C-terminus of bacterial DNA polymerase III alpha chain.

RPA2_OBF_family: A family of oligonucleotide binding (OB) folds with similarity to the OB fold of the single strand (ss) DNA-binding domain (DBD)-D of human RPA2 (also called RPA32). RPA2 is a subunit of Replication protein A (RPA). RPA is a nuclear ssDNA-binding protein (SSB) which appears to be involved in all aspects of DNA metabolism including replication, recombination, and repair. RPA also mediates specific interactions of various nuclear proteins. In animals, plants, and fungi, RPA is a heterotrimer with subunits of 70KDa (RPA1), 32kDa (RPA2), and 14 KDa (RPA3). RPA contains six OB folds, which are involved in ssDNA binding and in trimerization. The ssDNA binding mechanism is believed to be multistep and to involve conformational change. This family also includes OB folds similar to those found in Escherichia coli SSB, the wedge domain of E. coli RecG (a branched-DNA-specific helicase), E. coli ssDNA specific exodeoxyribonuclease VII large subunit, Pyrococcus abyssi DNA polymerase II (Pol II) small subunit, Sulfolobus solfataricus SSB, and Bacillus subtilis YhaM (a 3'-to-5'exoribonuclease). It also includes the OB folds of breast cancer susceptibility gene 2 protein (BRCA2), Oxytricha nova telomere end binding protein (TEBP), Saccharomyces cerevisiae telomere-binding protein (Cdc13), and human protection of telomeres 1 protein (POT1).

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.

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.

(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
