Bottom-Up Approach to Explore Alpha-Amylase Assisted Membrane Remodelling
Harshit Kumar, Sayar Mandal, Suhasi Gupta +7
Soluble alpha-amylases play an important role in the catabolism of polysaccharides. In this work, we show that the enzyme can interact with the lipid membrane and further alter its…
Non-Equilibrium Thermodynamics of Self-Replicating Protocells
Harold Fellermann, Bernat Corominas-Murtra, Per Lyngs Hansen +3
We provide a non-equilibrium thermodynamic description of the life-cycle of a droplet based, chemically feasible, system of protocells. By coupling the protocells metabolic kinetic…
Organelle morphogenesis by active remodeling
N. Ramakrishnan, John H. Ipsen, Madan Rao +1
Intracellular organelles are subject to a steady flux of lipids and proteins through active, energy consuming transport processes. Active fission and fusion are promoted by GTPases…
Membrane mediated aggregation of curvature inducing nematogens and membrane tubulation
N. Ramakrishnan, P. B. Sunil Kumar, John H. Ipsen
The shapes of cell membranes are largely regulated by membrane associated, curvature active, proteins. We use a numerical model of the membrane with elongated membrane inclusions,…
Role of disclinations in determining the morphology of deformable fluid interfaces
N. Ramakrishnan, John H. Ipsen, P. B. Sunil Kumar
We study the equilibrium shapes of vesicles, with an in-plane nematic order, using a Monte-Carlo scheme and show that highly curved shapes, like tubes and discs, with a striking si…
Modeling anisotropic elasticity of fluid membranes
N. Ramakrishnan, P. B. Sunil Kumar, John H. Ipsen
The biological membrane, which compartmentalizes the cell and its organelles, exhibit wide variety of macroscopic shapes of varying morphology and topology. A systematic understand…
