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 ... -
Design and evaluation of antimalarial peptides derived from prediction of short linear motifs in proteins related to erythrocyte invasion
(2015)The purpose of this study was to investigate the blood stage of the malaria causing parasite, Plasmodium falciparum, to predict potential protein interactions between the parasite merozoite and the host erythrocyte and ... -
Development of liquid culture media mimicking the conditions of sinuses and lungs in cystic fibrosis and health
(2022)The respiratory tract is a compartmentalised and heterogenous environment. The nasopharynx and sinuses of the upper airways have distinct properties from the lungs and these differences may shape bacterial adaptation ... -
Development of SFV-based plasmid electroporation for use in tumour treatment and vaccine delivery
(Trinity College (Dublin, Ireland). Department of Microbiology, 2008)Electroporation is the delivery of short and intense electric pulses into living cells (either in tissue or suspension), which results in a transient and reversible increase in permeability of the cell transmembrane. This ... -
The dipeptide repeat region of the fibrinogen-binding protein (clumping factor) is required for functional expression of the fibrinogen-binding domain on the Staphylococcus aureus cell surface.
(1997)Clumping factor of Staphylococcus aureus is a fibrinogen‐binding protein that is located on the bacterial cell surface. The protein has an unusual repeat domain (region R) comprising mainly the dipeptide aspartate and ... -
Discovery and engineering of antimicrobial peptides to combat food spoilage
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Microbiology, 2019)This work sought to use a bioinformatics based approach to discover plant derived antimicrobial peptides which were structurally similar to human β-defensin 3 (HBD3) and which possessed effective antimicrobial activity ... -
Distinct phenotypes and transcriptomes of tup1 and cyc8 mutants suggest novel roles for TUP1 and CYC8 in Saccharomyces cerevisiae
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Microbiology, 2023)The Tup1-Cyc8 (Ssn6) co-repressor complex is a regulator of gene transcription in the yeast Saccharomyces cerevisiae. This project provides insights into the distinct roles of Tup1p and Cyc8p in gene repression, identifies ... -
DNA supercoiling and the Lrp protein determine the directionality of fim switch DNA inversion in Escherichia coli K-12
(2006)Site-specific recombinases of the integrase family usually require cofactors to impart directionality in the recombination reactions that they catalyze. The FimB integrase inverts the Escherichia coli fim switch (fimS) in ... -
DNA supercoiling and transcription: a two-way street
(2019)Background : The processes of DNA supercoiling and transcription are interdependent because the movement of a transcription elongation complex simultaneously induces under- and over winding of the DNA duplex and because ... -
Downstream Effects of Haemoglobinase Inhibition in Plasmodium falciparum-Infected Erythrocytes
(2010)Blood-stage malarial parasites (Plasmodium falciparum) digest large quantities of host haemoglobin during their asexual development in erythrocytes. The haemoglobin digestion pathway, involving a succession of cleavages ... -
Drug Repurposing as a Strategy to Uncover Effective Antibacterial Compounds using Salmonella as a model
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Microbiology, 2021)Without doubt, antimicrobial resistance (AMR) is one of the most serious global challenge for public, animals and environmental health. Tackling this huge issue that is threatening modern medicine, is an urgent priority ... -
Ecological dependencies and the illusion of cooperation in microbial communities
(2024)Ecological dependencies - where organisms rely on other organisms for survival - are a ubiquitous feature of life on earth. Multicellular hosts rely on symbionts to provide essential vitamins and amino acids. Legume plants ... -
Ecological selection of siderophore-producing microbial taxa in response to heavy metal contamination
(2018)Some microbial public goods can provide both individual and community-wide benefits, and are open to exploitation by non-producing species. One such example is the production of metaldetoxifying siderophores. Here, we ... -
Effect of intranasal administration of Semliki Forest virus recombinant particles expressing interferon-? on the progression of experimental autoimmune encephalomyelitis.
(Spandidos, 2008)The effect of intranasal (IN) administration of Semliki Forest virus (SFV) recombinant particles expressing interferon-? [IFN-?, a partially effective treatment for multiple sclerosis (MS)] on the progression of experimental ...
