Cache domain; Double cache domain 1 covers the last three strands from the membrane distal PAS-like domain, the first two strands of the membrane proximal domain, and the connecting elements between the two domains. This domain when present in chemoreceptors recognize several signals such as proteinogenic amino acids, GABA, Histamine and polyamines, decanoic acid, Autoinducer-2, purine derivatives, quaternary amines, citrate and taurine, among others. When associated with histidine kinases, it recognizes C3/C4-dicarboxylic acids, Spermine, guanosine and Autoinducer-2 (Mantilla et al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1 https://doi.org/10.1093/femsre/fuab043).

Stage II sporulation protein E (SpoIIE); This family contains a number of bacterial stage II sporulation E proteins (EC:3.1.3.16). These are required for formation of a normal polar septum during sporulation. The N-terminal region is hydrophobic and is expected to contain up to 12 membrane-spanning segments.

Histidine kinase, Adenylyl cyclase, Methyl-accepting protein, and Phosphatase (HAMP) domain; HAMP is a signaling domain which occurs in a wide variety of signaling proteins, many of which are bacterial. The HAMP domain consists of two alpha helices connected by an extended linker. The structure of the Af1503 HAMP dimer from Archaeoglobus fulgidus has been solved using nuclear magnetic resonance, revealing a parallel four-helix bundle; this structure has been confirmed by cross-linking analysis of HAMP domains from the Escherichia coli aerotaxis receptor Aer. It has been suggested that the four-helix arrangement can rotate between the unusually packed conformation observed in the NMR structure and a canonical coiled-coil arrangement. Such rotation may coincide with signal transduction, but a common mechanism by which HAMP domains relay a variety of input signals has yet to be established.

first PDC (PhoQ/DcuS/CitA) domain of methyl-accepting chemotaxis proteins and similar domains; Members of this subfamily display varying domain architectures but all contain double PDC (PhoQ/DcuS/CitA) sensor domains. This model represents the first PDC domain of Methyl-accepting chemotaxis proteins (MCPs), Histidine kinases (HKs), and other similar domains. Many members contain both HAMP (HK, Adenylyl cyclase, MCP, and Phosphatase) and MCP domains, which are signalling domains that interact with protein partners to relay a signal. MCPs are part of a transmembrane protein complex that controls bacterial chemotaxis. HK receptors are part of two-component systems (TCS) in bacteria that play a critical role for sensing and adapting to environmental changes. Typically, HK receptors contain an extracellular sensing domain flanked by two transmembrane helices, an intracellular dimerization histidine phosphorylation domain (DHp), and a C-terminal kinase domain, with many variations on this theme. In the case of HKs, signals detected by the sensor domain are transmitted through DHp to the kinase domain, resulting in the phosphorylation of a conserved histidine residue in DHp; phosphotransfer to a conserved aspartate in its cognate response regulator (RR) follows, which leads to the activation of genes for downstream cellular responses.
