chromosome segregation protein SMC, common bacterial 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. This family represents the SMC protein of most bacteria. The smc gene is often associated with scpB (TIGR00281) and scpA genes, where scp stands for segregation and condensation protein. SMC was shown (in Caulobacter crescentus) to be induced early in S phase but present and bound to DNA throughout the cell cycle.

family of the cytolysin A (ClyA) family alpha pore-forming toxins (alpha-PFT) including Bacillus cereus HblB, Aeromonas hydrophila AhlB, Bacillus thuringiensis Cry6Aa and similar proteins; This family belongs to the ClyA family of alpha-PFT bacterial toxins. PFTs form the major group of virulence factors in many pathogenic bacteria and in general are critical components of the molecular offensive and defensive machinery of cells in all kingdoms of life. Bacterial PFTs facilitate the takeover of host resources by puncturing holes in the membrane. PFTs can be classified as alpha-PFTs and beta-PFTs depending on the secondary structures of their membrane component. Alpha-PFTs use a ring of amphipathic helices while beta-PFTs use a beta-barrel to construct the pore. Members of this family include the toxins: Bacillus cereus hemolysin binding component B (HblB or HBL-B) of the diarrheal enterotoxin hemolysin BL, Aeromonas hydrophila hemolytic (Ahl) component B (AhlB) of the tripartite AhlABC toxin, Vibrio cholerae cytotoxin motility associated killing factor A (MakA) cytotoxin, Xenorhabdus nematophila alpha-xenorhabdolysin (XaxA), Bacillus thuringiensis crystal 6Aa (Cry6Aa) parasporal crystal (Cry) toxin, and Bacillus cereus non-hemolytic enterotoxin (Nhe) component A (NheA) of the non-hemolytic enterotoxin Nhe, which, despite its name, is hemolytic, among others. In solution, ClyA proteins have an elongated, almost entirely alpha-helical structure, except for a short hydrophobic beta-hairpin known as the beta-tongue. Pore formation by ClyA requires circular oligomerization of the toxin by a sequential mechanism. This, in turn, concentrates the amphipathic helices in the center of the ring-like structure, forming a helical barrel that inserts into the membrane by a wedge-like mechanism. Compared with ClyA, NheA is almost entirely alpha-helical with an enlarged "head" domain, and an enlarged beta-tongue; it has been proposed that NheA could even form beta-barrel pores. Alpha-PFTs with similar structures are increasingly being found in eukaryotes, in particular as components of the immune systems of animals. This family may be distantly related to Escherichia coli alpha-PFT hemolysin E (HlyE, also known as ClyA or SheA).

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.

helix-rich Mycoplasma protein; Members of this family occur strictly within a subset of Mycoplasma species. Members average 750 amino acids in length, including signal peptide. Sequences are predicted (Jpred 3) to be almost entirely alpha-helical. These sequences show strong periodicity (consistent with long alpha helical structures) and low complexity rich in D,E,N,Q, and K. Genes encoding these proteins are often found in tandem. The function is unknown.
