Macromolecular crowding
Although you were born and educated in the USA, you've worked in the UK for over 11 years. What are your views on the different ways science is done in the two countries? I've probably been away from the States too long to judge! One thing that does stand out, however, is the difference in postgraduate (PhD) education and training. Most students in the UK get funding for a three-year PhD after ...
متن کاملAn upper limit for macromolecular crowding effects
BACKGROUND Solutions containing high macromolecule concentrations are predicted to affect a number of protein properties compared to those properties in dilute solution. In cells, these macromolecular crowders have a large range of sizes and can occupy 30% or more of the available volume. We chose to study the stability and ps-ns internal dynamics of a globular protein whose radius is ~2 nm whe...
متن کاملMacromolecular Crowding and Size Effects on Probe Microviscosity
Development of biologically relevant crowding solutions necessitates improved understanding of how the relative size and density of mobile obstacles affect probe diffusion. Both the crowding density and relative size of each co-solute in a mixture will contribute to the measured microviscosity as assessed by altered translational mobility. Using multiphoton fluorescent correlation spectroscopy,...
متن کاملCrowding and hydrodynamic interactions likely dominate in vivo macromolecular motion.
To begin to elucidate the principles of intermolecular dynamics in the crowded environment of cells, employing brownian dynamics (BD) simulations, we examined possible mechanism(s) responsible for the great reduction in diffusion constants of macromolecules in vivo from that at infinite dilution. In an Escherichia coli cytoplasm model comprised of 15 different macromolecule types at physiologic...
متن کاملEffects of macromolecular crowding on the collapse of biopolymers.
Experiments show that macromolecular crowding modestly reduces the size of intrinsically disordered proteins even at a volume fraction (ϕ) similar to that in the cytosol, whereas DNA undergoes a coil-to-globule transition at very small ϕ. We show using a combination of scaling arguments and simulations that the polymer size R̅(g)(ϕ) depends on x=R̅(g)(0)/D, where D is the ϕ-dependent distance bet...
