RESUMO
RNase A (1 mM) was incubated with glucose (0.4 M) at 37 degrees C for up to 14 days in phosphate buffer (0.2 M, pH 7.4), digested with trypsin and analysed by LC-MS. The major sites of fructoselysine formation were Lys(1), Lys(7), Lys(37) and Lys(41). Three of these sites (Lys(7), Lys(37) and Lys(41)) were also the major sites of N epsilon-(carboxymethyl)lysine formation.
