Resolving bacterial cell biology: from replisome dynamics to cell wall synthesis
Bacteria are ubiquitous single cellular organisms. Compared to eukaryotic cells, bacteria have two unique characteristics: the membrane-less nucleoid and the cell wall built of peptidoglycan (PG). In most bacteria, a single circular chromosome is compacted ...
EPFL2024Coordination between cell growth, division and chromosome replication cycles in mycobacteria
Propagation of microorganisms is based on three fundamental processes: cell growth, DNA replication, and cell division. Although important for antibacterial drug development, these processes are poorly understood in Actinobacteria, a medically important ph ...
EPFL2021Functional and structural characterization of Serratia marcescens ExbB: determinants of the interaction with HasB/TonB
ExbBD is part of a cytoplasmic membrane molecular motor driven by the proton-motive force. It belongs to the larger family of motors involved in nutriment import across the outer membrane of Gram-negative bacteria (ExbBD), flagellar rotation (MotAB) or lat ...
2021Interaction of Fluorescent Single-Walled Carbon Nanotubes with Photosynthetic Microbes
The discovery of carbon-based nanomaterials has impacted a variety of research areas in ways that could not be imagined three decades ago. Their unique combination of structural, optical, and electronic properties has made these nano-sized materials partic ...
EPFL2020A biphasic growth model for cell pole elongation in mycobacteria
Georg Fantner, John McKinney, Haig Alexander Eskandarian, Mélanie Thérèse Marie Hannebelle, Chiara Toniolo, Joëlle Xiao Yuan Ven, Gaëlle Madeleine Vuaridel
Mycobacteria grow by inserting new cell wall material in discrete zones at the cell poles. This pattern implies that polar growth zones must be assembled de novo at each division, but the mechanisms that control the initiation of new pole growth are unknow ...
2020A high-content RNAi screen reveals multiple roles for long noncoding RNAs in cell division
Genome stability relies on proper coordination of mitosis and cytokinesis, where dynamic microtubules capture and faithfully segregate chromosomes into daughter cells. With a high-content RNAi imaging screen targeting more than 2,000 human lncRNAs, we iden ...
2020Overlapping and essential roles for molecular and mechanical mechanisms in mycobacterial cell division
Georg Fantner, John McKinney, Adrian Pascal Nievergelt, Pascal Damian Odermatt, Haig Alexander Eskandarian, Mélanie Thérèse Marie Hannebelle
Mechanisms to control cell division are essential for cell proliferation and survival. Bacterial cell growth and division require the coordinated activity of peptidoglycan synthases and hydrolytic enzymes to maintain mechanical integrity of the cell wall. ...
2019Bacterial cell cycle dynamics: size regulation during exponential growth and role of polyphosphate during starvation response
Bacteria are the most diverse and abundant kingdom of life and have adapted to survive and thrive in habitats around the globe. When provided with ample nutrients they grow and divide at staggering rates, increasing their population exponentially. Upon nut ...
EPFL2019OsCAldOMT1 is a bifunctional O-methyltransferase involved in the biosynthesis of tricin-lignins in rice cell walls
Lignin is a phenylpropanoid polymer produced in the secondary cell walls of vascular plants. Although most eudicot and gymnosperm species generate lignins solely via polymerization of p-hydroxycinnamyl alcohols (monolignols), grasses additionally use a fla ...
2019Computational Analysis of the Mutual Constraints between Single‐Cell Growth and Division Control Models
John McKinney, Neeraj Dhar, Ambroise Roger Vuaridel
Three models of division control are proposed to achieve cell size homeostasis: sizer, timer, and adder. However, few published studies of division control take into account the dynamics of single‐cell growth and most assume that single‐cell growth is expo ...
