Methanogenesis from trimethylamine, dimethylamine or monomethylamine is initiated by a series of corrinoid-dependent methyltransferases. The non-homologous genes encoding the full-length methyltransferases each possess an in-frame UAG (amber) codon that does not terminate translation. The amber codon is decoded by a...

High-strength bioactive glass-ceramic A-W was soaked in various acellular aqueous solutions different in ion concentrations and pH. After soaking for 7 and 30 days, surface structural changes of the glass-ceramic were investigated by means of Fourier transform infrared reflection spectroscopy...

The semicarbazide-sensitive amine oxidases (SSAO) (EC 1.4.3.6) were believed to be detoxifying enzymes, primarily involved in the oxidative deamination of endogenous amines, such as methylamine and aminoacetone, together with some xenobiotic amines. However, it appears that the reaction products may...
