Abstract In the present study, 180 Persian sturgeon fries at releasing weight with average weight of 1.8 ± 0.6 g were exposed to three different salinity levels including 0 (fresh water), 6 and 12 ppt in 96-hour and 10-day periods for measuring their gill metabolites by H-NMR based metabolomics. The results showed that changes in salinity caused changes in the metabolites involving in osmotic ...
A mixture of threonine dehydrogenase and aminoacetone synthetase will catalyze the conversion of L-threonine to glycine. The overall reaction likely involves the conversion of L-threonine, NAD+, and CoA to glycine, NADH, and acetyl-CoA. Physical separation of L-threonine dehydrogenase from aminoacetone synthetase results in the formation of aminoacetone and CO2 from their substrates. A physical...
The threonine dehydrogenase (TDG) pathway is a significant route of threonine degradation, yielding glycine in experimental animals, but has not been accurately quantitated in humans. Therefore, the effect of a large excess of dietary threonine, given either as free amino acid (+Thr) or as a constituent of protein (+P-Thr), on threonine catabolism to CO(2) and to glycine was studied in six heal...
Threonine deaminase (l-threonine dehydratase EC 4.2.1.16) has been partially purified from a new extreme thermophilic bacterium, Thermus X-1, which is similar to T. aquaticus YT-1. The threonine deaminase of strain X-1 has a maximal rate of reaction at 85 to 90 C and is more thermostable than the threonine deaminase from mesophilic bacteria. The enzyme has an apparent molecular weight of 100,00...
