type II toxin-antitoxin (TA) system HipA family toxin similar to Escherichia coli HipA, a serine/threonine-protein kinase that phosphorylates Glu-tRNA-ligase (GltX), preventing it from being charged, leading to an increase in uncharged tRNA(Glu), and is also the toxin component of the HipA-HipB TA module

HipA-like C-terminal domain; The members of this family are similar to a region close to the C-terminus of the HipA protein expressed by various bacterial species (for example Swiss:P23874). This protein is known to be involved in high-frequency persistence to the lethal effects of inhibition of either DNA or peptidoglycan synthesis. When expressed alone, it is toxic to bacterial cells, but it is usually tightly associated with HipB, and the HipA-HipB complex may be involved in autoregulation of the hip operon. The hip proteins may be involved in cell division control and may interact with cell division genes or their products.

type II toxin-antitoxin sytem toxin HipA from Shewanella oneidensis and similar proteins; This family contains type II toxin-antitoxin (TA) system HipA family toxins similar to Shewanella oneidensis HipA, a serine/threonine-protein kinase that phosphorylates Glu-tRNA-ligase (GltX), preventing it from being charged, leading to an increase in uncharged tRNA(Glu). This induces amino acid starvation and the stringent response via RelA/SpoT and increased (p)ppGpp levels, which inhibits replication, transcription, translation and cell wall synthesis, reducing growth and leading to persistence and multidrug resistance. HipA is the toxin component of the HipA-HipB TA module that is a major factor in persistence and bioflim formation; its toxic effect is neutralized by its cognate antitoxin HipB. HipA, with HipB, acts as a a corepressor for transcription of the hipBA promoter. In the Shewanella oneidensis HipAB:DNA promoter complex, HipB forms a dimer that binds the duplex operator DNA, with each HipB monomer interacting with separate HipA monomers. The HipAB component of the complex is composed of two HipA and two HipB subunits.

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,

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
