摘要

Proteins are targets for photo-destruction due to absorption of incident light by endogenous chromophores. The near-UV light can induce changes in the protein structure due to the disruption of disulfide bonds upon excitation of a nearby Trp-residue. Mass spectroscopic data presented evidence that structural modification observed upon irradiation of goat alpha-lactalbumin at 290 nm results from tryptophan (Trp) mediated cleavage of disulfide bonds.
