ribonuclease, Rne/Rng family; This model describes ribonuclease G (formerly CafA, cytoplasmic axial filament protein A), the N-terminal domain of ribonuclease E in which ribonuclease activity resides, and related proteins. In E. coli, both RNase E and RNase G have been shown to play a role in the maturation of the 5' end of 16S RNA. The C-terminal half of RNase E (excluded from the seed alignment for this model) lacks ribonuclease activity but participates in mRNA degradation by organizing the degradosome.

S1_RNase_E: RNase E and RNase G, S1-like RNA-binding domain. RNase E is an essential endoribonuclease in the processing and degradation of RNA. In addition to its role in mRNA degradation, RNase E has also been implicated in the processing of rRNA, and the maturation of tRNA, 10Sa RNA and the M1 precursor of RNase P. RNase E associates with PNPase (3' to 5' exonuclease), Rhl B (DEAD-box RNA helicase) and enolase (glycolytic enzyme) to form the RNA degradosome. RNase E tends to cut mRNA within single-stranded regions that are rich in A/U nucleotides. The N-terminal region of RNase E contains the catalytic site. Within the conserved N-terminal domain of RNAse E and RNase G, there is an S1-like subdomain, which is an ancient single-stranded RNA-binding domain. S1 domain is an RNA-binding module originally identified in the ribosomal protein S1. The S1 domain is required for RNA cleavage by RNase E. RNase G is paralogous to RNase E with an N-terminal catalytic domain that is highly homologous to that of RNase E. RNase G not only shares sequence similarity with RNase E, but also functionally overlaps with RNase E. In Escherichia coli, RNase G is involved in the maturation of the 5' end of the 16S rRNA. RNase G plays a secondary role in mRNA decay.

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
