“…Besides formation of photoproducts within DNA, UV irradiation of DNP causes the formation of photoproducts in proteins and also formation of covalent links between proteins and DNA [6]. It can be expected that these changes may result in changes of interactions between proteins and DNA in the nucleoprotein complex or in disturbations in its higher order structure, which can both contribute to the observed changes in the CD spectra.…”

UV irradiation of the chromatin caused an increase of the positive circular dichroic band in the vicinity of 275 nm (corresponding to DNA) and a deepening of the negative band of proteins at about 225 nm. These changes in the circular dichroic spectrum are monotonous in the range of doses studied (less than 6 X 10(4) J.m-2). The increase of the positive circular dichroic band probably reflects the occurrence of local conformational changes in DNA, which include changes in base position (tilting, distance from helix axis) in the close neighborhood of photoproducts. The presence of photoproducts in chromatin reduces changes in its circular dichroic spectra with temperature.

“…The last full review of UV-induced cross-linking of proteins to nucleic acids, citing references up to 1973, is that of Smith (1976a). Two brief yearly reviews of the field have also appeared (Kornhauser, 1975; Sperling and Havron,I 977b). Reviews of limited aspects of the field have been published by Smith (1976c), Todd and Han (1976), Gordon (1976), Schimmel et aI.…”
