Visualization of transient encounter complexes in protein-protein association

Article Abstract:

Paramagnetic relaxation enhancement was used to demonstrate the existence and visualize the distribution of an ensemble of transient, non-specific encounter complexes under equilibrium conditions for a relatively weak protein-protein complex between the amino-terminal domain of enzyme I and the phosphocarrier protein HPr. Restrained rigid-body simulated annealing refinement against the paramagnetic relaxation enhancement data enables to obtain an atomic probability distribution map of the non-specific encounter complex ensemble that qualitatively correlates with the electrostatic surface potentials on the interacting proteins.

Life as we know it

Article Abstract:

The article focuses on segments of 'ultraconserved' DNA-sections that have stayed exactly same throughout recent vertebrate evolution and they are identical in humans, rats and mice.
