 226-347 7.39e-03

GAF domain; This domain is present in cGMP-specific phosphodiesterases, adenylyl and guanylyl cyclases, phytochromes, FhlA and NifA. Adenylyl and guanylyl cyclases catalyze ATP and GTP to the second messengers cAMP and cGMP, respectively, these products up-regulating catalytic activity by binding to the regulatory GAF domain(s). The opposite hydrolysis reaction is catalyzed by phosphodiesterase. cGMP-dependent 3',5'-cyclic phosphodiesterase catalyzes the conversion of guanosine 3',5'-cyclic phosphate to guanosine 5'-phosphate. Here too, cGMP regulates catalytic activity by GAF-domain binding. Phytochromes are regulatory photoreceptors in plants and bacteria which exist in two thermally-stable states that are reversibly inter-convertible by light: the Pr state absorbs maximally in the red region of the spectrum, while the Pfr state absorbs maximally in the far-red region. This domain is also found in FhlA (formate hydrogen lyase transcriptional activator) and NifA, a transcriptional activator which is required for activation of most Nif operons which are directly involved in nitrogen fixation. NifA interacts with sigma-54. This domain can bind biliverdine and phycocyanobilin (Matilla et al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1. https://doi.org/10.1093/femsre/fuab043).

anti-sigma F factor; This model describes the SpoIIAB anti-sigma F factor. Sigma F regulates spore development in B subtilis. SpoIIAB binds to sigma F, preventing formation of the transcription complex at the promoter. SpoIIAA (anti-anti-sigma F factor) binds to SpoIIAB to inhibit association with sigma F, however SpoIIAB can phosphorylate SpoIIAA, causing disassociation of the SpoIIAA/B complex. The SpoIIE phosphatase dephosphorylates SpoIIAA. [Regulatory functions, Protein interactions, Cellular processes, Sporulation and germination]

Phytochromes are regulatory photoreceptors in plants and bacteria which exist in two thermally-stable states that are reversibly inter-convertible by light: the Pr state absorbs maximally in the red region of the spectrum, while the Pfr state absorbs maximally in the far-red region. This domain is also found in FhlA (formate hydrogen lyase transcriptional activator) and NifA, a transcriptional activator which is required for activation of most Nif operons which are directly involved in nitrogen fixation. NifA interacts with sigma-54. This domain can bind biliverdine and phycocyanobilin (Matilla et al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1. https://doi.org/10.1093/femsre/fuab043).

 455-515 1.64e-06

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.

Histidine kinase-like ATPase domain of two-component sensor histidine kinases similar to Erythrobacter litoralis blue light-activated histidine kinase 2; This domain family includes the histidine kinase-like ATPase (HATPase) domain of blue light-activated histidine kinase 2 of Erythrobacter litoralis (EL346). Signaling commonly occurs within HK dimers, however EL346 functions as a monomer. Also included in this family are the HATPase domains of ethanolamine utilization sensory transduction histidine kinase (EutW), whereby regulation of ethanolamine, a carbon and nitrogen source for gut bacteria, results in autophosphorylation and subsequent phosphoryl transfer to a response regulator (EutV) containing an RNA-binding domain. Proteins having this HATPase domain also contain a histidine kinase dimerization and phosphoacceptor domain (HisKA); some have an accessory PAS sensor domain, while some have an N-terminal histidine kinase domain.

 460-507 5.39e-05

Histidine kinase-like ATPase domain of the chemotaxis protein histidine kinase CheA, and some hybrid sensor histidine kinases; This family includes the cytoplasmic histidine kinase (HK) CheA, a transmembrane receptor which, together with cytoplasmic adaptor protein (CheW), forms the lattice at the core of the chemosensory array that controls the cellular chemotaxis of motile bacteria and archaea. CheA forms a two-component signal transduction system (TCS) with the response regulator CheY. Proteins having this CheA-like HATPase domain generally also have a histidine-phosphotransfer domain, a histidine kinase homodimeric domain, and a regulatory domain; some are hybrid sensor histidine kinases as they contain a REC signal receiver domain.

 461-500 2.88e-04

Histidine kinase-like ATPase domain of SpoIIAB, an anti sigma-F factor and serine-protein kinase involved in regulating sigma-F during sporulation in Bacilli, and related domains; This family includes histidine kinase-like ATPase (HATPase) domain of SpoIIAB, an anti sigma-F factor and a serine-protein kinase involved in regulating sigma-F during sporulation in Bacilli where, early in sporulation, the cell divides into two unequal compartments: a larger mother cell and a smaller forespore. Sigma-F transcription factor is activated in the forespore directly after the asymmetric septum forms, and its spatial and temporal activation is required for sporulation. Free sigma-F can associate with the RNA polymerase core and activate transcription of the sigma-F regulon, its regulation may comprise a partner-switching mechanism involving SpoIIAB, SpoIIAA, and sigma-F as follows: SpoIIAB can form alternative complexes with either: i) sigma-F, holding it in an inactive form and preventing its association with RNA polymerase, or ii) unphosphorylated SpoIIAA and a nucleotide, either ATP or ADP. In the presence of ATP, SpoIIAB acts as a kinase to specifically phosphorylate a serine residue of SpoIIAA; this phosphorylated form has low affinity for SpoIIAB and dissociates, making SpoIIAB available to capture sigma-F. SpoIIAA may then be dephosphorylated by a SpoIIE serine phosphatase and be free to attack the SpoIIAB sigma-F complex to induce the release of sigma-F.

anti-sigma F factor; This model describes the SpoIIAB anti-sigma F factor. Sigma F regulates spore development in B subtilis. SpoIIAB binds to sigma F, preventing formation of the transcription complex at the promoter. SpoIIAA (anti-anti-sigma F factor) binds to SpoIIAB to inhibit association with sigma F, however SpoIIAB can phosphorylate SpoIIAA, causing disassociation of the SpoIIAA/B complex. The SpoIIE phosphatase dephosphorylates SpoIIAA. [Regulatory functions, Protein interactions, Cellular processes, Sporulation and germination]

 226-347 7.39e-03

GAF domain; This domain is present in cGMP-specific phosphodiesterases, adenylyl and guanylyl cyclases, phytochromes, FhlA and NifA. Adenylyl and guanylyl cyclases catalyze ATP and GTP to the second messengers cAMP and cGMP, respectively, these products up-regulating catalytic activity by binding to the regulatory GAF domain(s). The opposite hydrolysis reaction is catalyzed by phosphodiesterase. cGMP-dependent 3',5'-cyclic phosphodiesterase catalyzes the conversion of guanosine 3',5'-cyclic phosphate to guanosine 5'-phosphate. Here too, cGMP regulates catalytic activity by GAF-domain binding. Phytochromes are regulatory photoreceptors in plants and bacteria which exist in two thermally-stable states that are reversibly inter-convertible by light: the Pr state absorbs maximally in the red region of the spectrum, while the Pfr state absorbs maximally in the far-red region. This domain is also found in FhlA (formate hydrogen lyase transcriptional activator) and NifA, a transcriptional activator which is required for activation of most Nif operons which are directly involved in nitrogen fixation. NifA interacts with sigma-54. This domain can bind biliverdine and phycocyanobilin (Matilla et al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1. https://doi.org/10.1093/femsre/fuab043).
