Threonine Aldolases

2014
Threonine aldolases catalyze the pyridoxal phosphate-dependent condensation between small amino acids (principally glycine) and aldehydes such as acetaldehyde. Carbon-carbon bond formation involves forming two adjacent chiral centers. As a rule, threonine aldolases are very stereoselective for α-carbon configuration but show modest selectivity at the β-

Threonine Metabolism of Chicks Fed Threonine-Imbalanced Diets

The Journal of Nutrition, 1982
Experiments were conducted to determine the metabolic fate of threonine in chicks fed threonine-imbalanced diets. Threonine imbalance was produced by the addition of 3% serine to a threonine-limited diet, and prevented by the addition of 0.2% threonine to the diet.

Stereoselective synthesis of allo-threonine and β-2H-allo-threonine from threonine

Tetrahedron Letters, 1993
Abstract Both D- and L-allo-threonine can be synthesized in good yield from D- and L-threonine respectively, by protection of the amine with Fmoc and the carboxyl with a cyclic ortho ester, followed by oxidation of the side chain to a ketone, and diastereoselective reduction to the allo isomer.

Umbilical Threonine Uptake during Maternal Threonine Infusion in Sheep

Placenta, 2003
The infusion into the maternal circulation of amino acid solutions failed to increase umbilical threonine (THR) uptake above normal even when THR was present in the infusate at a relatively high concentration. The purpose of the present study was to determine whether umbilical THR uptake can be increased by infusing a THR solution that does not contain
