Mature MADH β subunit contains one exchangeable carbonyl at the C6 position of βW57. Sample preparation and mass spectrometry analysis were as previously described.9 Shown are deconvoluted mass spectra of the mature MADH β subunit. Green lines are after overnight incubation in buffer containing (A) H216O and (B) H218O, orange lines are after the further addition of a five-fold excess of hydrazine to each sample.
