High molecular weight glutenin subunit; Members of this family include high molecular weight subunits of glutenin. This group of gluten proteins is thought to be largely responsible for the elastic properties of gluten, and hence, doughs. Indeed, glutenin high molecular weight subunits are classified as elastomeric proteins, because the glutenin network can withstand significant deformations without breaking, and return to the original conformation when the stress is removed. Elastomeric proteins differ considerably in amino acid sequence, but they are all polymers whose subunits consist of elastomeric domains, composed of repeated motifs, and non-elastic domains that mediate cross-linking between the subunits. The elastomeric domain motifs are all rich in glycine residues in addition to other hydrophobic residues. High molecular weight glutenin subunits have an extensive central elastomeric domain, flanked by two terminal non-elastic domains that form disulphide cross-links. The central elastomeric domain is characterized by the following three repeated motifs: PGQGQQ, GYYPTS[P/L]QQ, GQQ. It possesses overlapping beta-turns within and between the repeated motifs, and assumes a regular helical secondary structure with a diameter of approx. 1.9 nm and a pitch of approx. 1.5 nm.

RecF/RecN/SMC N terminal domain; This domain is found at the N terminus of SMC proteins. The SMC (structural maintenance of chromosomes) superfamily proteins have ATP-binding domains at the N- and C-termini, and two extended coiled-coil domains separated by a hinge in the middle. The eukaryotic SMC proteins form two kind of heterodimers: the SMC1/SMC3 and the SMC2/SMC4 types. These heterodimers constitute an essential part of higher order complexes, which are involved in chromatin and DNA dynamics. This family also includes the RecF and RecN proteins that are involved in DNA metabolism and recombination.

chromosome segregation protein SMC, primarily archaeal type; SMC (structural maintenance of chromosomes) proteins bind DNA and act in organizing and segregating chromosomes for partition. SMC proteins are found in bacteria, archaea, and eukaryotes. It is found in a single copy and is homodimeric in prokaryotes, but six paralogs (excluded from this family) are found in eukarotes, where SMC proteins are heterodimeric. This family represents the SMC protein of archaea and a few bacteria (Aquifex, Synechocystis, etc); the SMC of other bacteria is described by TIGR02168. The N- and C-terminal domains of this protein are well conserved, but the central hinge region is skewed in composition and highly divergent.

Xenorhabdus nematophila alpha-xenorhabdolysin (XaxA) and Yersinia enterocolitica YaxA, and similar proteins; This model includes Xenorhabdus nematophila alpha-xenorhabdolysin (XaxA) and Yersinia enterocolitica YaxA, both parts of two-component alpha-helical pore-forming toxins (alpha-PFTs). The xaxAB genes encoding the XaxAB toxin have also been also identified in various plant and human pathogens. XaxAB triggers necrosis and apoptosis in both insect hemocytes and mammalian cells. Structure studies show that component A binds to component B's back, forming a subunit; twelve to fifteen of these subunits then conjoin as the pore-forming toxin. Component A stabilizes each subunit on the membrane and activates component B, which then punctures the membrane by swinging out its lower end. Similarly, Yersinia enterocolitica YaxA, encoded by the yaxAB gene, forms a pore predominantly composed of decamers of YaxA-YaxB heterodimers. Although both subunits bear membrane-active moieties, only YaxA is capable of binding to membranes by itself and YaxB is subsequently recruited to membrane-associated YaxA and induced to present its lytic transmembrane helices; pore formation then progresses by further oligomerization of YaxA-YaxB dimers. YaxAB has been found to be strongly upregulated by the Yersinia master regulator RovA, a transcriptional activator of Yersinia outer membrane protein invasion which is involved in bacterial attachment and invasion across the intestinal epithelium.

Mitotic checkpoint protein; This family consists of several eukaryotic mitotic checkpoint (Mitotic arrest deficient or MAD) proteins. The mitotic spindle checkpoint monitors proper attachment of the bipolar spindle to the kinetochores of aligned sister chromatids and causes a cell cycle arrest in prometaphase when failures occur. Multiple components of the mitotic spindle checkpoint have been identified in yeast and higher eukaryotes. In S.cerevisiae, the existence of a Mad1-dependent complex containing Mad2, Mad3, Bub3 and Cdc20 has been demonstrated.
