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 کاملMacromolecular Crowding Enhances Catalytic Efficiency and Stability of α-Amylase
In the present study an attempt was made to investigate the macromolecular crowding effect on functional attributes of α-amylase. High concentrations of sugar based cosolvents, (e.g., trehalose, sucrose, sorbitol, and glycerol) were used to mimic the macromolecular crowding environment (of cellular milieu) under in vitro conditions. To assess the effect of macromolecular crowding, the activity ...
متن کاملEffect of macromolecular crowding on protein binding stability: modest stabilization and significant biological consequences.
Macromolecular crowding has long been known to significantly affect protein oligomerization, and yet no direct quantitative measurements appear to have been made of its effects on the binding free energy of the elemental step of adding a single subunit. Here, we report the effects of two crowding agents on the binding free energy of two subunits in the Escherichia coli polymerase III holoenzyme...
متن کاملThe effects of macromolecular crowding on the mechanical stability of protein molecules.
Macromolecular crowding, a common phenomenon in the cellular environments, can significantly affect the thermodynamic and kinetic properties of proteins. A single-molecule method based on atomic force microscopy (AFM) was used to investigate the effects of macromolecular crowding on the forces required to unfold individual protein molecules. It was found that the mechanical stability of ubiquit...
متن کاملProtein diffusion and macromolecular crowding in thylakoid membranes.
The photosynthetic light reactions of green plants are mediated by chlorophyll-binding protein complexes located in the thylakoid membranes within the chloroplasts. Thylakoid membranes have a complex structure, with lateral segregation of protein complexes into distinct membrane regions known as the grana and the stroma lamellae. It has long been clear that some protein complexes can diffuse be...
