Amino Acid Sequence

Lys-Tyr-Lys

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.

Actions biochimiques/physiologiques

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

The effects of water on electron capture dissociation products, molecular survival, and recombination energy are investigated for diprotonated Lys-Tyr-Lys solvated by between zero and 25 water molecules. For peptide ions with between 12 and 25 water molecules attached, electron capture

OH.-induced covalent peptide-nucleotide adducts have been isolated by reverse-phase chromatography from the enzymic hydrolyzates of gamma-ray irradiated solutions containing double-stranded poly(deoxyadenylic-deoxythymidylic acid) and one of the tripeptides, lysyl-tryptophyl-lysine or lysyl-tyrosyl-lysine. Numerous compounds were formed, resulting presumably from different modes of

Exposure to UVA radiation of SV40 DNA substituted with bromodeoxyuridine (BrdU) in the presence of Hoechst dye 33258 results in the production of uracil. The yield of uracil was determined by measuring the increase in the single-strand break (SSB) yield

Tripeptides containing aromatic residues between basic ones, such as Lys-Trp-Lys and Lys-Tyr-Lys can nick supercoiled or relaxed DNAs containing apurinic/apyrimidinic sites (AP-sites). The nicking, which is ionic strength-dependent, occurs at AP-sites, since native PM2 DNA is not hydrolyzed. The nicking
