Threonine Imbalance and the Threonine Requirement of the Chicken
The Journal of Nutrition, 1982Experiments were conducted to determine the influence of dietary amino acids on the threonine requirement of chicks. A diet limiting in threonine and containing the equivalent of 20.6% crude protein was imbalanced by supplements of 0.9 to 1.5% L-tryptophan, 3.0% L-serine, a mixture of 2% each, leucine, isoleucine and valine or a 6.0% mixture of all ...

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

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.

Serine/threonine protein kinases
Current Opinion in Neurobiology, 1992Signal transduction in the nervous system is heavily dependent on the three multifunctional serine/threonine protein kinases, PKA, PKC, and CaM-KII. Recent studies have furthered our understanding of how the multiple isoforms of these kinases and their subcellular localizations, regulatory properties, and substrate determinants are important for the ...

Serine/threonine kinase receptors
Progress in Growth Factor Research, 1994A new family of transmembrane receptors that contain intracellular serine/threonine kinase domains is emerging. Ligands for this class of receptors include members of the transforming growth factor-beta (TGF-beta) superfamily, e.g. TGF-beta s and activins.

Protein serine/threonine phosphatases
Current Opinion in Biotechnology, 1996In the past year, the three-dimensional structures of two serine/threonine phosphatases, protein phosphatase-1 and protein phosphatase-2b (calcineurin), have been determined. The new information puts previous sequence comparisons and mutagenesis studies into a detailed structural perspective.

Phosphoserine/threonine-binding domains
Current Opinion in Cell Biology, 2001Phosphorylation of proteins on serine and threonine residues has traditionally been viewed as a means to allosterically regulate catalytic activity. Research within the past five years, however, has revealed that serine/threonine phosphorylation can also directly result in the formation of multimolecular signaling complexes through specific ...

Archives of Microbiology, 1996
Transmembrane threonine fluxes (i.e., uptake, diffusion, and carrier-mediated excretion) all contribut-ing to threonine production by a recombinant strain of Corynebacterium glutamicum, were analyzed and quantitated. A threonine-uptake carrier that transports threonine in symport with sodium ions was identified.
