Tryptophan protection of phage from ultraviolet irradiation
Description
Bacteriophage SP02c12 and its isolated DNA were irradiated at 254 nm in tryptophan solutions. At a concentration of 10 mM, the amino acid exerted a protective effect on intact virus. The magnitude of this effect depended upon the length of time elapsed between mixing and irradiation. No protection was observed for solutions irradiated immediately after mixing. Tryptophan did not have a significant effect on UV sensitivity of the isolated viral DNA. No covalent crosslinking of tryptophan to DNA was observed. (author)
