WebAbstract Crystallization is necessary to obtain the three-dimensional structure of proteins and nucleic acids; it often represents the bottleneck in structure determination. Our understanding of crystallization mechanisms is still incomplete. In this review, we emphasize fundamental aspects of the crystallization process. Protein-protein contacts … WebThe crystallization process is explained by Le Châtelier’s principle, which states that a system that is shifted away from equilibrium acts to restore equilibrium by reacting in opposition to the shift. So an increase in temperature causes the system to decrease energy, in an attempt to bring the temperature down.
