Ethylmaleimide 64-80 tumor protein p53 Homo sapiens 161-164 21472523-3 2011 Using a combination of top-down and middle-down FTICR mass spectrometry, we show that of the 10 Cys residues in the core domain of wild-type p53, Cys182 and Cys277 exhibit a remarkable preference for modification by the alkylating reagent N-ethylmaleimide. Ethylmaleimide 239-255 tumor protein p53 Homo sapiens 141-144
