Peptides singlet oxygen oxidation

The dependence on pH of an extrinsic band in the c.d. spectrum of a lysozyme with tryptophan-62 selectively (2-nitrophenylsulphenyl)ated has been studied. Analysis of the peptides in tryptic hydrolysates of two forms of lysozyme oxidized with singlet oxygen established that tryptophan-62 is destroyed. This was confirmed by the effect exerted by chitin, which protected tryptophan-62 from oxidation. The possible oxidation of other tryptophanyl residues by singlet oxygen was also discussed. [Pg.417]
