Abstract
Dietary exposure biomarkers are needed for advancing knowledge on healthy foods. This study examined biomarkers for navy beans and rice bran in children and adults. Plasma, urine, stool, and study foods from dietary intervention studies were analyzed by metabolomics. A total of 38 children and 49 adults were assessed after consuming navy beans and/or rice bran for 2-, 4-, 6-, or 12 weeks. From the 138-175 metabolites modulated by diet, 11 were targeted for quantification. Trigonelline and pipecolate concentrations increased in children and adult plasma after 4 weeks compared to baseline. Increased xanthurenate (46%) was observed in children plasma after rice bran intake for 4 weeks. Study foods with navy beans had higher S-methylcysteine compared to control and supported the increased urine S-methylcysteine sulfoxide. Nontargeted metabolomics was moderately effective to identify target molecules as candidate biomarkers. Study limitations include interindividual metabolite variations before diet intervention. Validation is warranted using cross-over designs and larger sample sizes.

Abstract
Glutamine synthetase (GS) is highly active in astrocytes, and these cells are physiologically and morphologically compromised by hyperammonemia. Hyperammonemia in end-stage acute liver failure (ALF) is often associated with cerebral edema and astrocyte pathology/swelling. Many studies of animal models of hyperammonemia, and, more recently, nuclear magnetic resonance studies of liver disease patients, have shown that cerebral glutamine is elevated in hyperammonemia, contributing to the edema and encephalopathy. The GS inhibitor L-methionine-S,R-sulfoximine (MSO) is protective in animal models against acute ammonia intoxication. MSO is also an inhibitor of glutamate cysteine ligase, is converted to metabolic products, and causes convulsions at high doses. However, the susceptibility to MSO-induced convulsions is species dependent, with primates being relatively resistant. Moreover, it is possible to chronically maintain cerebral GS activity in mice at low levels by MSO treatment without any obvious untoward effects. Furthermore, MSO is protective in a mouse model of ALF. Extreme caution would be needed in administering MSO to patients. Nevertheless, inhibition of brain GS by MSO (or other GS inhibitors) may have therapeutic benefit in ALF.

Abstract
R,R'-disubstituted sulfoximines were phosphorylated with O,O-diethylchloro phosphate and phosphorothionate to obtain new organophosphorus compounds. After purification they were characterized by GC-MS and (1)H-NMR. The toxicity of the synthesized O,O-diethyl N-(R,R'-disubstituted sulfoximine) phosphoro-amidothionates was assayed on Musca domestica. It was found that the methyl phenyl derivative was the most toxic compound, followed by the dipropyl and dibutyl derivatives. The dihexyl compound was the less toxic of all the assayed compounds, being one hundred times less toxic than a paraoxon standard The anticholinesterasic activity of the corresponding phosphoramidates was assayed on homogenates of house flies' heads, giving values similar to paraoxon for the methyl phenyl derivative.

Abstract
Carefully designed molecules that are intimately related to the reaction mechanism of enzymes are often highly selective and potent inhibitors that serve as extremely useful chemical probes for understanding the reaction mechanism and structure of enzymes. This article describes the design, synthesis, and applications of specific inhibitors of two mechanistically distinct groups of enzymes, ATP-dependent amide ligases and Ser- and Thr-hydrolases. Our strategy is based on the premise that stable analogues of the transition state (transition-state analogues) are highly potent inhibitors that serve as good mechanistic probes, and that a key structure of a good inhibitor of one enzyme is also utilized for the inhibitors of other enzymes that share the same chemistry in their catalyzed reactions, irrespective of the degree of structural similarity and evolutionary link between the enzymes. According to these principles, we designed and synthesized a series of phosphinate- and sulfoximine-based transition-state analogue inhibitors of glutathione synthetase, gamma-glutamylcysteine synthetase and asparagine synthetase. For the second group of enzymes, we synthesized a gamma-monofluorophosphono glutamate analogue for mechanism-based affinity labeling of gamma-glutamyltranspeptidase and fluorescent phosphonic acid esters for the active-site titration of lipase. These inhibitors were used successfully as ligands for detailed kinetic analyses, X-ray crystallography, and mass analysis of the enzymes to identify the key amino acid residues responsible for catalysis and substrate recognition in the transition state.

Abstract
Pseudomonas tabaci produces a toxin, tabtoxin, that causes wildfire disease in tobacco. The primary target of tabtoxin is presumed to be glutamine synthetase. Some effects of tabtoxin in tobacco can be mimicked by methionine sulfoximine (MSO), a compound that is known to inactivate glutamine synthetase. To understand how organisms can be made resistant to tabtoxin and MSO, we used Saccharomyces cerevisiae. We demonstrate that yeast strains carrying the glutamine synthetase gene, GLN1, on a multicopy plasmid overproduced glutamine synthetase and showed increased drug resistance. These and other data indicate that glutamine synthetase is the primary target of tabtoxin and MSO in S. cerevisiae. We also isolated three S. cerevisiae DNA inserts of 2.1, 2.3, and 2.8 kilobases that conferred tabtoxin and MSO resistance when the inserts were present on a multicopy plasmid. These plasmids conferred resistance to MSO by blocking intracellular transport of the drug. Transport appeared to occur by one or more methionine permeases. Resistance to tabtoxin could also occur by blockage of intracellular transport, but the drug was transported by some permease other than a methionine permease. These drug resistance plasmids did not block transport of citrulline, indicating that they did not affect the general amino acid permease.

Abstract
Regulation of the synthesis and activity of glutamine synthetase (GS) in the cyanobacterium Anabaena sp. strain 7120 was studied by determining GS transferase activity and GS antigen concentration under a variety of conditions. Extracts prepared from cells growing exponentially on a medium supplemented with combined nitrogen had a GS activity of 17 mumol of gamma-glutamyl transferase activity per min per mg of protein at 37 degrees C. This activity doubled in 12 h after transfer of cells to a nitrogen-free medium, corresponding to the time required for heterocyst differentiation and the start of nitrogen fixation. Addition of NH3 to a culture 11 h after an inducing transfer immediately blocked the increase in GS activity. In the Enterobacteriaceae, addition of NH3 after induction results in the covalent modification of GS by adenylylation. The GS of Anabaena is not adenylylated by such a protocol, as shown by the resistance of the transferase activity of the enzyme to inhibition by Mg2+ and by the failure of the enzyme to incorporate 32P after NH3 upshift. Methionine sulfoximine inhibited Anabaena GS activity rapidly and irreversibly in vivo. After the addition of methionine sulfoximine to Anabaena, the level of GS antigen neither increased nor decreased, indicating that Glutamine cannot be the only small molecule capable of regulating GS synthesis. Methionine sulfoximine permitted heterocyst differentiation and nitrogenase induction to escape repression by NH3. Nitrogen-fixing cultures treated with methionine sulfoximine excreted NH3. The fern Azolla caroliniana contains an Anabaena species living in symbiotic association. The Anabaena species carries out nitrogen fixation sufficient to satisfy all of the combined nitrogen requirements of the host fern. Experiments by other workers have shown that the activity of GS in the symbiont is significantly lower than the activity of GS in free-living Anabaena. Using a sensitive radioimmune assay and a normalization procedure based on the content of diaminopimelic acid, a component unique to the symbiont, we found that the level of GS antigen in the symbiont was about 5% of the level in free-living Anabaena cells. Thus, the host fern appears to repress synthesis of Anabaena GS in the symbiotic association.

Abstract
The convulsant agent methionine sulfoximine inhibits brain glutamine synthetase irreversibly and the inhibitor becomes bound to the active site of the enzyme as methionine sulfoximine phosphate. Only one of the four isomers of methionine sulfoximine, L-methionine-S-sulfoximine, inhibits glutamine synthetase. In the present work, D-methionine-SR-sulfoximine, and highly purified preparations of L-methionine-S-sulfoximine and L-methionine-R-sulfoximine were tested in mice for convulsant activity; only L-methionine-S-sulfoximine produced convulsions. The finding that only one of the four optical isomers of methionine sulfoximine induces convulsions, and that only this same isomer inhibits glutamine synthetase, lends support to the conclusion that these two effects of methionine sulfoximine are closely connected.
