The discovery that certain proteins may require zinc for their activity, and the fact that several of them cannot be purified in large amounts, has led us to develop a rapid, sensitive method to detect these proteins in samples. This method is based on the fractionation of the proteins by gel electrophoresis, blotting onto nitrocellulose paper, and overlaying with /sup 65/Zn. We have tested the procedure with well-characterized zinc-binding proteins. In the case of tubulin, we have used this method to localize its zinc-binding site. It was found that zinc binds to the first 150 amino acids of both alpha- and beta-tubulin subunits.
