Paracoccus denitrificans PD1222 accumulates short-length polyhydroxyalkanoates, poly(3-hydroxybutyrate), under nitrogen-deficient conditions. Polyhydroxybutyrate metabolism requires the 3-ketoacyl-CoA thiolase PhaA, the acetoacetyl-CoA dehydrogenase/reductase PhaB and the synthase PhaC for polymerization. Additionally, P. denitrificans PD1222 grows aerobically with nitrate as sole nitrogen sour...
Valinomycin-induced uptake of rubidium by membrane vesicles prepared from Escherichia coli, Staphylococcus QUreus, and Micrococcus denifrificans is analogous in nearly all respects to the transport of sugars or amino acids, or both, by these membrane vesicles. In E. coli membrane vesicles, concentrative rubidium uptake is stimulated maximally by D-lactate and by the artificial electron donor as...
Although the reversible oxidation of free n-/3-hydroxybutyrate to acetoacetate in animal tissues was first observed many years ago (1, 2), relatively little is known about the properties and intracellular distribution of the dehydrogenase responsible for this reaction. In 1937 Green et al. (3) described a stereospecific diphosphopyridine nucleotide-linked n-P-hydroxybutyric dehydrogenase in res...
Both enantiomers of 15-hexadecanolide, a sex pheromone component of the stink bug (Piezodorus hybneri), were synthesized by using the Yamaguchi or Mitsunobu macrolactonization reaction of (R)-15-hydroxyhexadecanoic acid prepared from ethyl (R)-β-hydroxybutyrate in 5 steps.
