A new protein superfamily includes two novel 3-methyladenine DNA glycosylases from Bacillus cereus, AlkC and AlkD
Alseth, Ingrun; Rognes, Torbjørn; Lindbäck, Toril; Solberg, Inger; Robertsen, Kristin; Kristiansen, Knut Ivan; Mainieri, Davide; Lillehagen, Lucy; Kolstø, Anne-Brit; Bjørås, M. (Journal article; Peer reviewed, 2006)Soil bacteria are heavily exposed to environmental methylating agents such as methylchloride and may have special requirements for repair of alkylation damage on DNA. We have used functional complementation of an Escherichia ... -
Biochemical and mutational analysis of spore cortex-lytic enzymes in the food spoiler Bacillus licheniformis
Aspholm, Marina; Kollerud, Kristian K; Høgberg Hansen, Helge C; Granum, Per Einar; Christie, Graham; Lindbäck, Toril (Journal article; Peer reviewed, 2019)Bacillus licheniformis is frequently associated with food spoilage due to its ability to form highly resistant endospores. The present study reveals that B. licheniformis spore peptidoglycan shares a similar structure to ... -
Commensal E. coli Stx2 lysogens produce high levels of phages after spontaneous prophage induction.
Iversen, Hildegunn; L'Abee-Lund, Trine Marie; Aspholm, Marina; Arnesen, Lotte Pia Stenfors; Lindbäck, Toril (Journal article; Peer reviewed, 2015) -
Culture dependent and independent analyses suggest a low level of sharing of endospore-forming species between mothers and their children
Avershina, Ekaterina; Larsen, Marte Gro; Aspholm, Marina Elisabeth; Lindbäck, Toril; Storrø, Ola; Øien, Torbjørn; Johnsen, Roar; Rudi, Knut (Peer reviewed; Journal article, 2020)Spore forming bacteria comprise a large part of the human gut microbiota. However, study of the endospores in gut microbiota is limited due to difficulties of culturing and numerous unknown germination factors. In this ... -
Endospore Appendages: a novel pilus superfamily from the endospores of pathogenic Bacilli
Pradhan, Brajabandhu; Liedtke, Janine; Sleutel, Mike; Lindbäck, Toril; Zegeye, Ephrem Debebe; O_Sullivan, Kristin; Llarena, Ann-Katrin; Brynildsrud, Ola Brønstad; Aspholm, Marina Elisabeth; Remaut, Han (Peer reviewed; Journal article, 2021)Bacillus cereus sensu lato is a group of Gram-positive endospore-forming bacteria with high ecological diversity. Their endospores are decorated with micrometer-long appendages of unknown identity and function. Here, we ... -
High diversity in the regulatory region of Shiga toxin encoding bacteriophages
Fagerlund, Annette; Aspholm, Marina; Wegrzyn, Grzegorz; Lindbäck, Toril (Peer reviewed; Journal article, 2022)Background: Enterohemorrhagic Escherichia coli (EHEC) is an emerging health challenge worldwide and outbreaks caused by this pathogen poses a serious public health concern. Shiga toxin (Stx) is the major virulence factor ... -
MogR is a ubiquitous transcriptional repressor affecting motility, biofilm formation and virulence in Bacillus thuringiensis
Smith, Veronika; Josefsen, Malin; Lindbäck, Toril; Hegna, Ida Kristin; Finke, Sarah; Tourasse, Nicolas Jacques; Nielsen-LeRoux, Christina; Økstad, Ole Andreas; Fagerlund, Annette (Journal article; Peer reviewed, 2020-12)Flagellar motility is considered an important virulence factor in different pathogenic bacteria. In Listeria monocytogenes the transcriptional repressor MogR regulates motility in a temperature-dependent manner, directly ... -
Replication Region Analysis Reveals Non-lambdoid Shiga Toxin Converting Bacteriophages
Llarena, Ann-Katrin; Aspholm, Marina Elisabeth; O_Sullivan, Kristin; Wêgrzyn, Grzegorz; Lindbäck, Toril (Peer reviewed; Journal article, 2021)Shiga toxin is the major virulence factor of enterohemorrhagic Escherichia coli (EHEC), and the gene encoding it is carried within the genome of Shiga toxin-converting phages (Stx phages). Numerous Stx phages have been ... -
