New sulfoximine- and phenanthrene-based photochemical precursors to oxynitrenes have been developed. These precursors have been used to examine the chemistry and spectroscopy of oxynitrenes. The first EPR spectra of oxynitrenes are reported and are consistent with their triplet ground states. Additional support for the triplet ground state of oxynitrenes is provided by trapping and reactivity s...
The application of glutathione to immature soybean cotyledons reduced the accumulation of the beta subunit of beta-conglycinin, and increased the accumulation of most glycinins. Both reduced and oxidized forms of glutathione had these effects. The application of an inhibitor of glutathione synthesis, buthionine sulfoximine, increased accumulation of beta subunit. These results suggest that glut...
Stichococcus bacillaris Naeg., a green soil alga, can grow in the presence of methionine sulfoximine (MSX), an inhibitor of glutamine synthetase, by maintaining a high level of NADPH-glutamate dehydrogenase activity. MSX-grown cells can utilize both NH(4) (+) and NO(3) (-) as nitrogen source for growth. [(14)C]Methylammonium is not metabolized by S. bacillaris, and is transported by a carrier s...
