Applicazioni

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.

Azioni biochim/fisiol

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

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

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

The complete sequential assignment and conformation of d-GpCpGpC in D2O has been determined from 1D NMR spectra at 285-320 K and room temperature 2D-COSY and NOESY spectra. The tetradeoxynucleotide exists primarily as a right handed double helix at 285 K
