The ability of tryptophan in peptides to photosensitize the oxidation of methyl linoleate (ML) was evaluated. Purified ML was irradiated (λ > 270 nm) alone or in the presence of a tryptophan‐containing peptide in ethanol solution. Oxidation was monitored by measuring the dienc hydroperoxides formed from ML by high performance liquid chromatography. N‐acetylphenylalanyltryptophan (NAPT) and N‐acetyltryptophan were about 2‐fold more effective as photosensitizers than leucyltryptophan and… Expand

Interest of photochemical methods for induction of lipid peroxidation.
TLDR
The principles of the reactions, the photosensitizers that can be employed to generate the various reactive species of oxygen, and the techniques, direct (ESR) or indirect (specific traps), used to detect the reactive species are described. Expand

TLDR
The results indicate that the major effects of UV radiation on cell membranes are alterations of proteins and suggest that tryptophan is the major chromophore for these alterations. Expand

MECHANISMS OF PHOTOSENSITIZATION
This review discusses important developments in the area of photosensitization from approximately June, 1982, through June, 1983. For the most part the articles cited will represent in vitro work,Expand

TLDR
Elicitation of the most effective nasal immunogenicity in dye‐inactivated vaccines appeared to depend on selective modification of capsid protein or ribose in viral core with dyes possessing definite functions, despite the different molecular structures. Expand

N‐FORMYL‐KYNURENINE, A TRYPTOPHAN PHOTOOXIDATION PRODUCT, AS A PHOTODYNAMIC SENSITIZER
TLDR
Photodynamic properties of a tryptophan ultraviolet‐photooxidation product, N‐formylkynurenine, were investigated with amino acids and nucleotides as substrates and Lifetime computations from kinetic and quenching experiments suggest that sensitization occurs via the N‐ formyl‐kynureine triplet state.

The mechanism of the smooth thermal rearrangement of the (presumably ring-chain tautomeric) tryptophan hydroperoxy intermediates to formylkynurenine is discussed with its implications for the biological oxidation by tryPTophan 2,3-dioxygenase. Expand
Flash photolysis of enzymes.
TLDR
This analysis indicates that hen lysozyme and papain are inactivated by photolysis of an essential Trp residue, that bovine trypsin is inactivation by photofullysis of a Trp residues adjacent to the key catalytic Ser and other pathways initiated by excitation of Tyr and Cys, and that aromatic residues in subtilisn Carlsberg are photosensitive.
