[...]Based on the fragmentation pattern of methylglucoasmine, we developed a method to distinguish and quantify C1 and C2 (13)C-labeled glucose by derivatization with methylamine followed by multiple reaction monitoring scans in a Q-trap mass spectrometer. Fragment ion ratios in the tandem mass spectra showed an isotope effect with (13)C or [...]

[...]In this theoretical study, we investigate the impact of structural and conformational variations on the electronic coupling between the redox proteins methylamine dehydrogenase and amicyanin from Paracoccus denitrificans. We used molecular dynamics simulations to generate configurations over a duration of 40 ns (sampled at 100-fs intervals) in conjunction with an [...]

[...]The mechanism of H and D atom loss, following ultraviolet photolysis of methylamine-d(3), CD(3)NH(2), has been studied via electronic action and Doppler spectroscopies. The N-H bond is preferentially cleaved and the yield of both H and D photofragments increases gradually, but differently, as higher vibrational states on the first excited electronic state, A, are accessed, leading to some drop in H/D branching ratios.[...]
