Application

Lysyltyrosyllysine (Lys-Tyr-Lys, KYK) is used together with uracil DNA glycosylase to quantify uracil. Lysyltyrosyllysine is also used as a model peptide to study free radical oxidation and electron capture mechanisms.

Biochem/physiol Actions

Tripeptide can induce nicks at apurinic/apyrimidinic sites in circular DNA.
