| Description | This entry represents the C-terminal activator domain of pesticin.Pesticin (Pst) is an anti-bacterial toxin produced by Yersinia pestis that acts through uptake by the target related bacteria and the hydrolysis of peptidoglycan in the periplasm. It is referred to as a bacteriocin and it leads to the hydrolysis of peptidoglycan. Its immunity protein is Pim. Pesticin carries an elongated N-terminal translocation domain, an intermediate receptor binding domain, and a C-terminal activity domain with structural analogy to lysozyme homologues. The full-length protein is toxic to bacteria when taken up to the target site via the outer or the inner membrane [ ].Bacteriocins such as pesticin are produced by gram-negative bacteria to attack related bacterial stains. Pst is transported to the periplasm via FyuA, an outer-membrane receptor of Y. pestis and E. coli, where it hydrolyzes peptidoglycan via the cleavage of N-acetylmuramic acid and C4 of N-acetylglucosamine. Disruption of the peptidoglycan layer renders the bacteria vulnerable to lysis via osmotic pressure. The pesticin C-terminal domain resembles the lysozyme-like family, which includes soluble lytic transglycosylases (SLT), goose egg-white lysozymes (GEWL), hen egg-white lysozymes (HEWL), chitinases, bacteriophage lambda lysozymes, endolysins, autolysins, and chitosanases. All the members are involved in the hydrolysis of beta-1,4- linked polysaccharides. [ , , ]. | Name | Pesticin, C-terminal |
