A number of sulfur-containing amino acids, in addition tomethionine, are substrates of rat kidney, rat brain, bovine brain, and bovine kidney GTKs in vitro. These include cysteine,S-methylcysteine,homocysteine,ethionine,methionine sulfoxide, methioninesulfone,methionine sulfoximine,cystine,cystathionine,...
(+32) residues]. In addition, multiple peptides containingN-formylkynurenine, as well as nitratedtyrosinein combination withmethionine sulfoxideor sulfone, can also be observed (data not shown). In contrast,nitrationoftryptophan residuesalone was not detected. Peptides, containing oxidized derivatives ...
One simple possible reason for the blunted response to MetR in the aged flies is that their internal Met levels might not have been decreased to the same extent as in young flies. To test this hypothesis, we measured Met and its metabolites by LC-MS/MS analysis (Fig.3g–r). The whole...
The concentrations of metabolites were normalised by methionine sulfone and the body weight of flies or protein amount in the haemolymph. For body weight measurement, flies were anaesthetised by CO2 and placed on a microbalance (METTLER TOLEDO, XPR2). The mass spectrometry raw data generated in ...
Methionine (Met) can be oxidized to Met sulfoxide (MetO) or Met sulfone (MetO2) with potential deleterious, antioxidant, or regulatory effects. Other residues, like proline (Pro), can undergo carbonylation. Using the white-rot Pycnoporus cinnabarinus grown on aspen wood, we analyzed the Met ...
Further, the MetSOx can be further oxidized to form a corresponding sulfone, but this process requires a stronger oxidant; hence, this conversion is not easily accomplished in vivo and is not an easily reversible process. The mechanism of free radical oxidation of sulfur...
Similarly, dibenzothiophene sulfone monooxygenase (DszA) is involved in biodesulfurization in Rhodococcus erythropolis [45, 46] and repressed by both l-methionine and l-cysteine. If a similar regulation occurs in fungi, it Bischof et al. Microb Cell Fact (2015) 14:120 Page 8 of 11 would ...
The oxidation of the epimers of sulindac to sulindac sulfone has also been characterized, and the members of the cytochrome P450 family involved in the oxidation have been identified.Florida Atlantic University.Brunell, David J.Florida Atlantic University....
