Tyrosinase inhibition by peptides may find its application in food, cosmetics or medicine. In order to identify novel tyrosinase inhibitory peptides, protein-based peptide libraries made by SPOT synthesis were used to screen for peptides that show direct interaction with tyrosinase. One of the peptide libraries studied consists of overlapping, octameric peptides derived from industrial proteins as ß-casein, ¿-lactalbumin, ß-lactoglobulin, ovalbumin, gliadin, glycinin, and ß-conglycinin. On-membrane activity staining resulted in a set of peptides that are not only able to bind to tyrosinase, but are able to inhibit tyrosinase as well. Peptides containing aspartic or glutamic acid residues usually do not bind very well to tyrosinase. Strong tyrosinase-binding peptides always contain one or more arginine residues, often in combination with phenylalanine, while lysine residues can be found equally among nonbinding peptides as well as moderate tyrosinase-binding peptides. The presence of the hydrophobic, aliphatic residues valine, alanine or leucine appears to be important for tyrosinase inhibition. Therefore, good tyrosinase inhibitory peptides preferably contain arginine and/or phenylalanine in combination with valine, alanine and/or leucine.
