摘要：
B12 in a new light: The B12 derivative hydroxocobalamin can be used as an efficient catalyst for light-induced strand cleavage of DNA. The proposed radical process involves hydroxy radicals and is controlled by visible light (see scheme). Such light-controlled radical reactions promise to be particularly useful in intracellular applications. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
