Association kinetics of wild-and mutant-type Ynd1p in relation to quality of grown crystals

Article Abstract:

Dynamic and time-resolved static light scattering measurements are used to investigate the intermolecular interaction and association dynamics of the Ynd1p protein. Fractal dimension analysis using scattering intensity data suggested that the inner structure of the aggregates changed from loose to rigid with time and single crystals of Ynd1p grew in the mutant-type protein solution, while polycrystals of Ynd1p grew in the wild-type protein solution.

Assembly kinetics of bc1 complex membrane protein investigated by using a continuous-angle laser light scattering technique

Article Abstract:

The assembly kinetics of a membrane protein, the bc1 complex, is investigated using a newly developed continuous-angle laser light scattering technique. The assembly process of the bc1 complex increases both the size of the aggregates and the compactness of the internal structure. The assembly rate is controlled by the presence of zinc as well as by the concentration of PEG, the crystallizing reagent.
