VapC-like PIN domain of Thermus Thermophilus Hb8, uncharacterized Bacillus subtilis YacL, and other bacterial homologs; PIN (PilT N terminus) domain of the conserved membrane protein of unknown function of Thermus Thermophilus Hb8, Bacillus subtilis YacL and other similar homologs are included in this family. This subgroup belongs to the VapC (virulence-associated protein C)-like family of the PIN domain nuclease superfamily. VapC is the PIN-domain ribonuclease toxin from prokaryotic VapBC toxin-antitoxin (TA) systems. VapB is a transcription factor-like protein antitoxin acting as an inhibitor. Other members of the VapC-like nuclease family include FitB toxin of the FitAB TA system, eukaryotic ribonucleases such as Smg6, ribosome assembly factor NOB1, exosome subunit Rrp44 endoribonuclease and rRNA-processing protein Fcf1. The structural properties of the PIN domain indicate its active center, consisting of three highly conserved catalytic residues which coordinate metal ions; in some members, additional metal coordinating residues can be found while some others lack several of these key catalytic residues. The PIN active site is geometrically similar in the active center of structure-specific 5' nucleases, PIN-domain ribonucleases of eukaryotic rRNA editing proteins, and bacterial toxins of toxin-antitoxin (TA) operons. Proteins in this group have a C-terminal TRAM domain whose function is unknown but predicted to be a RNA-binding domain common to tRNA uracil methylation and adenine thiolation enzymes.

VapC-like PIN domain of an uncharacterized AAA+, VirB11-like ATPase-, KH- and PIN-domain containing protein MJ1533 from Methanocaldococcus jannaschii DSM 2661, and other similar archaeal homologs; PIN (PilT N terminus) domain present N-terminal of AAA+, VirB11-like ATPases. Several members of this subfamily possess an AAA+, VirB11-like ATPase domain, flanked by PIN and KH nucleic acid-binding domains. VirB11-ATPase is a type IV secretory pathway component required for T-pilus biogenesis and virulence. This subgroup belongs to the VapC (virulence-associated protein C)-like family of the PIN domain nuclease superfamily. VapC is the PIN-domain ribonuclease toxin from prokaryotic VapBC toxin-antitoxin (TA) systems. VapB is a transcription factor-like protein antitoxin acting as an inhibitor. Other members of the VapC-like nuclease family include FitB toxin of the FitAB TA system, eukaryotic ribonucleases such as Smg6, ribosome assembly factor NOB1, exosome subunit Rrp44 endoribonuclease and rRNA-processing protein Fcf1. The structural properties of the PIN domain indicate its active center, consisting of three highly conserved catalytic residues which coordinate metal ions; in some members, additional metal coordinating residues can be found while some others lack several of these key catalytic residues. PIN domains within this subgroup contain four of these highly conserved residues which cluster at the C-terminal end of the beta-sheet and form a negatively charged pocket near the center of the molecule. The PIN active site is geometrically similar in the active center of structure-specific 5' nucleases, PIN-domain ribonucleases of eukaryotic rRNA editing proteins, and bacterial toxins of toxin-antitoxin (TA) operons.

The PIN active site is geometrically similar in the active center of structure-specific 5' nucleases, PIN-domain ribonucleases of eukaryotic rRNA editing proteins, and bacterial toxins of toxin-antitoxin (TA) operons. Matelska et al. recently classified PIN-like domains and included distant subgroups, this subgroup includes some sequences belonging to one of these, PIN_14.

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.

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) 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
