Time-resolved CIDNP study of native-state bovine and human alpha-lactalbumins

Abstract:

The reaction mechanism and details of the formation of CIDNP (chemically induced dynamic nuclear polarization) in the photoreactions of two aromatic dyes (2,2′-dipyridyl, DP, and flavin mononucleotide, FMN) with bovine and human α-lactalbumins (BLA and HLA) in aqueous solution have been studied using the time-resolved CIDNP technique. With DP as the photosensitizer, polarization in BLA is observed for the protons of Trp118, His68, Tyr18, and Tyr103. The latter is not manifested in the CIDNP s...
