Journal ArticleDOI
Application of Bacteriocins in the Control of Foodborne Pathogenic and Spoilage Bacteria
TL;DR: Application of bacteriocins may help reduce the use of chemical preservatives and/or the intensity of heat and other physical treatments, satisfying the demands of consumers for foods that are fresh tasting, ready to eat, and lightly preserved.
Journal ArticleDOI
Peptide AS-48: prototype of a new class of cyclic bacteriocins.
Mercedes Maqueda,Antonio Gálvez,Manuel Martinez Bueno,María José Sánchez-Barrena,Carlos González,Armando Albert,Manuel Rico,Eva Valdivia +7 more
TL;DR: The three-dimensional structure of bacteriocin AS-48 is solved, and it consists of a globular arrangement of five alpha-helices enclosing a compact hydrophobic core, being the first example of a posttranslational modification in which a cyclic structure arises from a "head-to-tail" linkage.
Journal ArticleDOI
Genetic features of circular bacteriocins produced by Gram-positive bacteria
Mercedes Maqueda,Marina Sánchez-Hidalgo,Matilde Fernández,Manuel Montalbán-López,Eva Valdivia,Manuel Martínez-Bueno +5 more
TL;DR: This review highlights the main genetic features of circular bacteriocins, which require the co-ordinated expression of several genetic determinants, and summarizes the progress made in the understanding of their principal genetic features over the last few years.
Journal ArticleDOI
Bacteriocin AS-48, a microbial cyclic polypeptide structurally and functionally related to mammalian NK-lysin
Carlos González,Grant M. Langdon,Marta Bruix,Antonio Gálvez,Eva Valdivia,Mercedes Maqueda,Manuel Rico +6 more
TL;DR: The solution structure of bacteriocin AS-48, a 70-residue cyclic polypeptide from Enterococcus faecalis, consists of a globular arrangement of five alpha-helices enclosing a compact hydrophobic core that most probably determine its antibacterial activity by promoting pore formation in cell membranes.
Journal ArticleDOI
Characterization and safety evaluation of enterococci isolated from Spanish goats' milk cheeses
TL;DR: This study characterized 95 enterococci isolated from 3 different goats' milk cheeses, belonging to the species Enterococcus devriesei,Enterococcus faecalis and E. malodoratus, among others, and found that the genotypes tended to be specific to particular cheeses; only two of the different cheeses contained two genotypes.
