YP_003041995.1 Penicillin-binding protein 5 functions as a D-alanyl-D-alanine carboxypeptidase. Its precise function is unknown; it may mediate interactions with other cell wall-synthesising enzymes, thus allowing the protein to be recruited to areas of active cell wall synthesis. It may also function as a linker domain that positions the active site in the catalytic domain closer to the peptidoglycan layer, to allow it to interact with cell wall peptides YP_003042000.1 cold shock-like protein YP_003042007.1 Functionally, this transport system is involved in osmoregulation. Under conditions of stress, the organism recruits this transport system to accumulate glycine betaine and other solutes which offer osmo-protection.

TerC has been implicated in resistance to tellurium, and may be involved in efflux of tellurium ions. YP_003042471.1 similar to unknown protein yrap of escherichia coli YP_003042480.1 SspB is encoded in an operon whose synthesis is stimulated by carbon, amino acid, and phosphate starvation. YP_003042481.1 stringent starvation protein regulator YP_003042522.1 PmbA facilitates the secretion of microcin B17 (MccB17) the by completing its maturation . Microcin B17 (MccB17) is a peptide antibiotic produced by E. coli strains harbouring plasmid pMccB17. YP_003042526.1 This group of peptidases belong to MEROPS peptidase family U62 (clan U-). The type example is microcin-processing peptidase 1 from Escherichia coli, which is the product of the gene PmbA. It has been suggests that the pmbA gene product acts to inhibit the interaction between the letD protein and the A subunit of DNA gyrase. The letA (ccdA) and letD (ccdB) genes of the F plasmid, located just outside the sequence essential for F-plasmid replication, contribute to stable maintenance of the plasmid in E. coli cells. The letD gene product acts to inhibit partitioning of chromosomal DNA and cell division by inhibiting DNA gyrase activity, whereas the letA gene product acts to reverse the inhibitory activity of the letD gene product. YP_003042530.1 Maf is a putative inhibitor of septum formation in eukaryotes, bacteria, and archaea. YP_003042533.1 the gene products localise close to the cell surface, forming filamentous helical structures. Many homologues have been found in diverse bacterial groups, suggesting a common ancestor . The crystal structure of MreB from Thermotoga maritima has been resolved using X-ray crystallography . It consists of 19 beta-strands and 15 alpha- helices, and shows remarkable structural similarity to eukaryotic actin. MreB crystals also contain proto-filaments, with individual proteins assembling into polymers like F-actin, in the same orientation. It is hypothesised therefore, that MreB was the forerunner of actin in early eukaryotes. YP_003042545.1 The MFS transporters are single-polypeptide secondary carriers capable only of transporting small solutes in response to chemiosmotic ion gradients YP_003042547.1 This family contains insecticidal toxins produced by Bacillus species of bacteria. During spore formation the bacteria produce crystals of this protein. When an insect ingests these proteins they are activated by proteolytic cleavage. The N-terminus is cleaved in all of the proteins and a C-terminal extension is cleaved in some members. Once activated the endotoxin binds to the gut epithelium and causes cell lysis by the formation of cation-selective channels, which leads to death. The activated toxin is composed of three distinct domains: an N-terminal helical bundle domain involved in membrane insertion and pore formation; a beta-sheet domain involved in receptor binding; and a C-terminal beta-sandwich domain that interacts with the N-terminal domain to form a channel , . This entry represents the conserved N-terminal domain. YP_003042562.1 putative multidrug-efflux transporter YP_003042582.1 Members of this family which have been characterized, belong to the small multidrug resistance (Smr) protein family and are integral membrane proteins. They confer resistance to a wide range of toxic compounds by removing them for the cells. The efflux is coupled to an influx of protons. YP_003042609.1 similar to toxic ion resistance protein YP_003042612.1 putative invasin YP_003042616.1 Most of the bacterial outer membrane proteins in this group are porin-like integral membrane proteins YP_003042622.1 putative fha-family protein YP_003042673.1 putative peptidase YP_003042674.1 This family contains integral membrane proteins that are related to Drosophila rhomboid protein . Members of this family are found in archaea, bacteria and eukaryotes. Analysis suggests that Rhomboid-1 is a novel intramembrane serine protease that directly cleaves the membrane-anchored TGF-alpha-like growth factor Spitz, allowing it to activate the Drosophila EGF receptor YP_003042675.1 Photopexin AB YP_003042688.1 In Gram-negative bacteria the biogenesis of fimbriae (or pili YP_003042689.1 fimbrial protein YP_003042690.1 found in flagellar protein J (), which has been shown to hydrolyse peptidoglycan YP_003042730.1 similar to pyocin s3 immunity protein YP_003042731.1 This family includes bacterial colicin and pyocin immunity proteins. These immunity proteins can bind specifically to the DNase-type colicins and pyocins and inhibit their bactericidal activity. YP_003042732.1 Bacteriocins are protein antibiotics that kill bacteria closely related to the producing species. Colicins are a subgroup of bacteriocins that are produced by and target Escherichia coli. The lethal action of most colicins is exerted either by formation of a pore in the cytoplasmic membrane of the target cell, or by an enzymatic nuclease digestion mechanism. YP_003042733.1 Pyocins are polypeptide toxins produced by, and active against, bacteria. S-type pyocins cause cell death by DNA breakdown due to endonuclease activity YP_003042751.1 similar to lactate oxidase YP_003042775.1 similar to adenine-specific methylase yhdj YP_003042811.1 Beta-lactamase catalyses the opening and hydrolysis of the beta-lactam ring of beta-lactam antibiotics such as penicillins and cephalosporins YP_003042819.1 similar to extracellular solute-binding protein-amino acid abc transporter YP_003042869.1 penicillin-binding protein YP_003042936.1 antitoxin of the YoeB-YefM toxin-antitoxin system YP_003042942.1 Drug resistance/sensitivity to chloramphenicol YP_003042988.1 emrA confers resistance to carbonylcyanide m-chlorophenylhydrazone, nalidixic acid, and a number of other toxic compounds. YP_003042989.1 emrB confers resistance to carbonylcyanide m-chlorophenylhydrazone, nalidixic acid, and a number of other toxic compounds. YP_003043047.1 BFR and ferritin are a family of iron-storage proteins found in both eukaryotes and bacteria . Common to both ferritins and BFRs is a capacity to store large quantities of iron within their hollow interior, in the form of a hydrated ferric oxide mineral containing variable amounts of phosphate anion. YP_003043048.1 iron storage regulator YP_003043069.1 tcda2 YP_003043073.1 met regulon regulatory protein YP_003043076.1 transcriptional repressor YP_003043082.1 similar to unknown protein yiiu of escherichia coli YP_003043086.1 Multidrug resistance proteins are molecular pumps that participate in a low energy shock adaptive response in some bacteria. They mediate cellular resistance to toxicants YP_003043096.1 yacb-transcriptional repressor YP_003043097.1 Plasmids may be maintained stably in bacterial populations through the action of addiction modules, in which a toxin and antidote are encoded in a cassette on the plasmid. In any daughter cell that lacks the plasmid, the toxin persists and is lethal after the antidote protein is depleted. Toxin/antitoxin pairs are also found on main chromosomes, and likely represent selfish DNA. Sequences in the seed for this alignment all were found adjacent to toxin genes. Several toxin/antitoxin pairs may occur in a single species. RelE and RelB form a toxin-antitoxin system; RelE represses translation, probably through binding ribosomes , . RelB stably binds RelE, presumably deactivating it.
