Abstract: The present invention relates to a method for the crystallization of protein using nanoparticles as nucleation agents. Precisely, the inventors performed the crystallization of such proteins as Bacillus subtilis YesR, chicken egg white lysozyme, bovine serum albumin, Alicyclobacillus acidocaldarius acetyl-CoA carboxylase, and Listeria monocytogenes hypothetical protein which have his-tag at amino terminal by using gold nanoparticles in diverse sizes and shapes in the presence of Ni2+ ions. As a result, it was confirmed that the chance of successful crystallization was higher with the gold nanoparticles than without the gold nanoparticles and the various crystallization conditions were successfully screened. Therefore, the method for inducing nucleation of the invention can be advantageously used for the disclosure of protein structure by increasing the chance of successful crystallization of protein.
