Threonine Metabolism of Chicks Fed Threonine-Imbalanced Diets
The Journal of Nutrition, 1982Experiments 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.

Influence of threonine exporters on threonine production in Escherichia coli
Applied Microbiology and Biotechnology, 2002Threonine production in Escherichia coli threonine producer strains is enhanced by overexpression of the E. coli rhtB and rhtC genes or by heterologous overexpression of the gene encoding the Corynebacterium glutamicum threonine excretion carrier, thrE. Both E.

Threonine kinetics at graded threonine intakes in young men
The American Journal of Clinical Nutrition, 1986A study was undertaken in eight healthy young men to examine the effects of varying intakes of threonine on plasma free threonine concentrations and threonine kinetics, using a 3 h constant intravenous infusion of L-[1-13C]threonine. Subjects consumed diets based on an L-amino acid mixture, in which the quality of threonine was reduced every 7 days. On

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-

L-Threonine is an essential amino acid which has recently been brought into agricultural industry for balancing the livestock feed. L-Threonine is produced by microbial synthesis using glucose or sucrose as substrates. For the process to be cost-effective, the microbial strain must be capable of threonine overproduction.

Umbilical Threonine Uptake during Maternal Threonine Infusion in Sheep
Placenta, 2003The 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

Threonine dehydrogenase is a minor degradative pathway of threonine catabolism in adult humans [PDF]
American Journal of Physiology-Endocrinology and Metabolism, 2000 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 ...

Quantitative partition of threonine oxidation in pigs: effect of dietary threonine
American Journal of Physiology-Endocrinology and Metabolism, 1990Kinetic aspects of threonine (Thr) metabolism were examined in eight pigs fed hourly with a diet containing either 0.68% (LT group) or 0.81% (HT group) of Thr (wt/wt), corresponding to 10 and 30% Thr excess, respectively, compared with an "ideal" diet.
