Amino Acid Sequence

Lys-Tyr-Lys

應用

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.

生化／生理作用

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

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

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
