GAF domain; The GAF domain is named after some of the proteins it is found in, including cGMP-specific phosphodiesterases, adenylyl cyclases and FhlA. It is also found in guanylyl cyclases and phytochromes. The structure of a GAF domain shows that the domain shares a similar fold with the PAS domain. This domain can bind O2, CO and NO (Matilla et.al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1. https://doi.org/10.1093/femsre/fuab043).

Histidine kinase-like ATPase domain of RsbW, an anti sigma-B factor and serine-protein kinase involved in regulating sigma-B during stress in Bacilli, and related domains; This family includes histidine kinase-like ATPase (HATPase) domain of RsbW, an anti sigma-B factor as well as a serine-protein kinase involved in regulating sigma-B during stress in Bacilli. The alternative sigma factor sigma-B is an important regulator of the general stress response of Bacillus cereus and B. subtilis. RsbW is an anti-sigma factor while RsbV is an anti-sigma factor antagonist (anti-anti-sigma factor). RsbW can also act as a kinase on RsbV. In a partner-switching mechanism, RsbW, RsbV, and sigma-B participate as follows: in non-stressed cells, sigma-B is present in an inactive form complexed with RsbW; in this form, sigma-B is unable to bind to RNA polymerase. Under stress, RsbV binds to RsbW, forming an RsbV-RsbW complex, and sigma-B is released to bind to RNA polymerase. RsbW may then act as a kinase on RsbV, phosphorylating a serine residue; RsbW is then released to bind to sigma-B, hence blocking its ability to bind RNA polymerase. A phosphatase then dephosphorylates RsbV so that it can again form a complex with RsbW, leading to the release of sigma-B.

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.

(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)
