Structural studies of Burkholderia pseudomallei invasion protein D (BipD), 2,4'-dihydroxyacetophenone dioxygenase (DAD) and L-threonine dehydrogenase (TDH)
… archaeon Thermococcus kodakaraensis (TkTDH) is involved in the first of a two-step biochemical pathway conversion of threonine to glycine, by catalysing the NAD+ dependent metabolism of L-threonine to 2-amino-3-ketobutyrate (KBL). The structure of this enzyme has been determined to 2.4 A …

The Role of Amino Acids and the Threonine-SAM Pathway in the Development of Bovine Inner Cell Mass and Pluripotency
… The role of the threonine dehydrogenase (TDH)-mediated threonine-s-adenosylmethionine (SAM) pathway in bovine ICM development and pluripotency in bovine embryos and cells was also investigated. This metabolic pathway has been shown to play a critical role in sustaining mouse pluripotency. …

Avaliação da remoção de matéria orgânica e sólidos suspensos em reatores UASB e hibrido
… operados com os tempos de detenção hidráulica (TDH) de 12, 8, 6, e 4 horas, com cerca de 80 dias de operação para cada TDH. A avaliação dos reatores foi feita através de análises físico-químicas de duas coletas semanais do afluente e efluente e, a cada mudança de TDH, fez-se o perfíl de sólidos. …

A comparison of the performance of Namibia-specific conservation and conventional tillage technologies as used for pearl millet production in northern Namibia
… (CV) treatments (i.e. tractor-drawn disc harrow (TDH) and animal-drawn mouldboard plough (AMP) were compared to two NSCT treatments (tractor-drawn ripper furrower (TRF) and animal-drawn ripper furrower (ARF). There were four specific objectives. The first objective is to compare the field …

Existing regulatory circuitries govern backbone and acquired host association factors in the human pathogen Vibrio parahaemolyticus
… expression of the classic virulence marker tdh was enhanced in a GacA mutant at 37°C; however the mutant was defective at initiating an infection in mice potentially discounting the relevance of TDH in disease. Though TDH is currently accepted as a clinical identifier, further work may …

The mechanism by which manganese protects Escherichia coli from hydrogen peroxide
… deformylase (PDF), threonine dehydrogenase (TDH) and cytosine deaminase (CDA). We showed that these enzymes use iron as their cofactor, and that manganese functionally replaces iron and therefore protects these enzymes when cells are stressed with H2O2. We believe iron is frequently …

Characterization of VIBRIO Parahaemolyticus-Induced Intestinal Inflammation in the Mouse
… response is extended in the presence of TDH. In addition to delineating the roles of the virulence factors TDH, type III secretion system 1, and type III secretion system 2, in the infection process, we have developed an experimental system that will enable further characterization of …

Symbiotic Associations and Pathogenic Potential of Vibrios In the North Inlet Estuary
… marker genes thermostable direct hemolysin (tdh) and thermostable direct hemolysin-related hemolysin (trh). Newly designed primers were employed for PCR reactions targeting tdh and trh which were found to be substantially more effective than older commonly employed primers. The genes encoding …

Superoxide stress in Escherichia coli
… Four such enzymes -- threonine dehydrogenase (Tdh), ribulose-5-phosphate 3-epimerase (Rpe), peptide deformylase (PDF), and DAHP synthase -- were shown to be inactivated in the Escherichia coli strain which lacks the ability to scavenge O2- (denoted as SOD- mutant). Moreover, the inactivation of …

Computational modeling techniques for biological network productivity increases : optimization and rate-limiting reaction detection
… bottleneck identification in this network. The TDH reaction was detected as a major bottleneck restricting carbon flow towards the ethanol pathway and affecting NADH availability. To manipulate the network for desired production rates of target metabolites, we developed an optimization technique …
