We serendipitously discovered that streptavidin crystals form instantaneously upon mixing streptavidins with positively or negatively charged peptides at their C-termini. Hybrid crystals of streptavidin with charged oligo-peptides, oligo-DNA, and dendrimers were also obtained via interaction between the charged peptides on streptavidins and the small charged molecules. This technique uses simple electrostatic interaction between the charged peptides; therefore it should be applicable to many proteins, defying the stereotypes about protein crystallization and facilitating the use of protein crystals as functional materials.}, pages = {3891--3894}, title = {Genetically fused charged peptides induce rapid crystallization of protein.}, volume = {56}, year = {2020} }
