pH-Dependent Decarboxylation of 2-Amino-3-ketobutyrate, the Unstable Intermediate in the Threonine Dehydrogenase-Initiated Pathway for Threonine Utilization
(Elsevier, 1993-02-15)
2-Amino-3-ketobutyrate can be readily formed enzymatically by the action of L-threonine dehydrogenase. A convenient assay for determining the half-life of this [beta]-keto acid is afforded by its rapid and quantitative ...
Milk composition and lactational output in the greater spear-nosed bat, Phyllostomus hastatus
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-07)
Growth rates of mammalian young are closely linked to the ability of the mother to provide nutrients; thus, milk composition and yield provide a direct measure of maternal investment during lactation in many mammals. We ...
Genetic and physical characterization of a region of Arabidopsis chromosome 1 containing the CLAVATA1 gene
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-01)
With the advance of Arabidopsis as a model system for understanding plant genetics, development and biochemistry, a detailed description of the genome is necessary. As such, focused projects are underway to map and sequence ...
Effects of host switching on gypsy moth ( Lymantria dispar (L.)) under field conditions
(Springer-Verlag, 1994-03)
Effects of various single and two species diets on the performance of gypsy moth ( Lymantria dispar (L.)) were studied when this insect was reared from hatch to population on intact host trees in the field. The tree species ...
Predicting cleavability of peptide sequences by HIV protease via correlation-angle approach
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1993-06)
In designing HIV protease inhibitors as potential drugs for AIDS therapy, knowledge about what peptide sequences in polyproteins are cleavable by HIV proteases is very useful. In this article, based on the formulation that ...
Corticotropin-releasing hormone ( Crh ) maps to mouse Chromosome 3
(Springer-Verlag; Springer-Verlag New York, Inc., 1993-10)
Pyrroloquinoline Quinone Acts with Flavin Reductase to Reduce Ferryl Myoglobin in Vitro and Protects Isolated Heart from Reoxygenation Injury
(Elsevier, 1993-05-28)
Pyrroloquinoline quinone has been isolated from bacteria and recently has been detected in mammalian tissues and fluids. We report in vitro studies which show that pyrroloquinoline quinone serves as a high-affinity substrate ...
Nitrate deposition in northern hardwood forests and the nitrogen metabolism of Acer saccharum marsh
(Springer-Verlag, 1996-10)
It is generally assumed that plant assimilation constitutes the major sink for anthropogenic Nitrate NO 3 − deposited in temperate forests because plant growth is usually limited by nitrogen (N) availability. Nevertheless, ...
Model Complexity has a Significant Effect on the Numerical Value and Interpretation of Metabolic Sensitivity Coefficients
(Elsevier, 1993-04-07)
Logarithmic sensitivity coefficients were promulgated for the analysis of metabolic regulation about 20 years ago. Interest in their use has risen significantly since their introduction. However, no comprehensive evaluation ...
Antinociceptive effects of [D-Ala2]deltorphin II, a highly selective [delta] agonist in vivo
(Elsevier, 1990)
The present study has characterized the antinociceptive actions of [D-Ala2]deltorphin II following intracerebroventricular (i.c.v.) administration in the mouse tail-flick test. [D-Ala2]deltorphin II produced dose- and ...
