Clumping factor A interaction with complement factor I increases C3b cleavage on the bacterial surface of Staphylococcus aureus, and decreases complement-mediated phagocytosis
(2010)The human complement system is important in the immunological control of Staphylococcus aureus infection. We showed previously that S. aureus surface protein clumping factor A (ClfA), when expressed in recombinant form, ... -
Clumping factor A of Staphylococcus aureus inhibits phagocytosis by human polymorphonuclear leucocytes
(2006)Staphylococcus aureus is a major cause of nosocomial and community-acquired infection. It expresses several factors that promote avoidance of phagocytosis by polymorphonuclear leucocytes. Clumping factor A (ClfA) is a ... -
Co-operative roles for DNA supercoiling and nucleoid-associated proteins in the regulation of bacterial transcription
(2013)DNA supercoiling and NAPs (nucleoid-associated proteins) contribute to the regulation of transcription of many bacterial genes. The horizontally acquired SPI (Salmonella pathogenicity island) genes respond positively to ... -
A common theme in interaction of bacterial immunoglobulin-binding proteins with immunoglobulins illustrated in the equine system
(The American Society for Biochemistry and Molecular Biology, 2008)The M protein of Streptococcus equi subsp. equi known as fibrinogen-binding protein (FgBP) is a cell wall-associated protein with antiphagocytic activity that binds IgG. Recombinant versions of the seven equine IgG subclasses ... -
Community composition drives siderophore dynamics in multispecies bacterial communities.
(2023)Background Intraspecific public goods are commonly shared within microbial populations, where the benefits of public goods are largely limited to closely related conspecifics. One example is the production of iron-scave ... -
Competing for Iron: Duplication and Amplification of the isd Locus in Staphylococcus lugdunensis HKU09-01 Provides a Competitive Advantage to Overcome Nutritional Limitation
(2016)Staphylococcus lugdunensis is a coagulase negative bacterial pathogen that is particularly associated with severe cases of infectious endocarditis. Unique amongst the coagulase-negative staphylococci, S. lugdunensis harbors ... -
Complement regulator C4BP binds to Staphylococcus aureus surface proteins SdrE and Bbp inhibiting bacterial opsonization and killing.
(2013)Staphylococcus aureus is a premier human pathogen and the most common cause of osteoarticular, wound, and implanted device infections. We recently demonstrated S. aureus efficiently binds the classical complement regulator ... -
Complete bypass of restriction systems for major staphylococcus aureus lineages
(2015)Staphylococcus aureus is a prominent global nosocomial and community-acquired bacterial pathogen. A strong restriction barrier presents a major hurdle for the introduction of recombinant DNA into clinical isolates of S. ... -
The complex and dynamic genomes of industrial yeasts
(2009)The Saccharomyces sensu stricto genus contains many species that are industrially important for fermentation of wines, beers and ales. The molecular characterization of the genomes of yeasts involved in these processes ... -
Consequences of producing DNA gyrase from a synthetic gyrBA operon in Salmonella enterica serovar Typhimurium
(2021)DNA gyrase is an essential type II topoisomerase that is composed of two subunits, GyrA and GyrB and has an A 2 B 2 structure. Although both subunits are required in equal proportions to form DNA gyrase, the gyrA and gyrB ... -
Contact transmission of influenza virus between ferrets imposes a looser bottleneck than respiratory droplet transmission allowing propagation of antiviral resistance
(2016)Influenza viruses cause annual seasonal epidemics and occasional pandemics. It is important to elucidate the stringency of bottlenecks during transmission to shed light on mechanisms that underlie the evolution and propagation ... -
Control of virulence gene transcription by indirect readout in Vibrio cholerae and Salmonella enterica serovar Typhimurium
(2017)Indirect readout mechanisms of transcription control rely on the recognition of DNA shape by transcription factors (TFs). TFs may also employ a direct readout mechanism that involves the reading of the base sequence in the ... -
Cultivating antimicrobial resistance: how intensive agriculture ploughs the way for antibiotic resistance
(2023)Antimicrobial resistance (AMR) is a growing threat to public health, global food security and animal welfare. Despite efforts in antibiotic stewardship, AMR continues to rise worldwide. Anthropogenic activities, particularly ... -
Deletion map of the chloramphenicol resistance region of R1 and R100-1
(1973)Recombination between single-site and multisite chloramphenicol-sensitive mutants of the F-like R factors R1 and R100-1 indicates that the chloramphenicol resistance region is a single structural gene coding for the ... -
Deletion of the nuclear exosome component RRP6 leads to continued accumulation of the histone mRNA HTB1 in S-phase of the cell cycle in Saccharomyces cerevisiae.
(2007)The nuclear exosome, a macromolecular complex of 3 ’ to 5 ’ exonucleases, is required for the post- transcriptional processing of a variety of RNAs including rRNAs and snoRNAs. Additionally, this complex forms part ... -
Deletions in the r-determinant mer region of plasmid R100-1 selected by loss of mercury hypersensitivity
(1979)A mutant of plasmid R100-1, which conferred cellular hypersensitivity to Hg2+ because of the insertion of Tn801 (TnA) into the gene determining synthesis of mercuric reductase enzyme, allowed further mutational events to ... -
Design and characterisation of food grade powders and inks for microstructure control using 3D printing
(2018)Additive Manufacturing techniques have been previously applied to food materials with direct consumption in mind, as opposed to creating structural ingredients as shown in this study. First, semi-crystalline cellulose was ...
