Two years later, Kornberg invited Horecker and Leon Heppel to join him in setting up a new Section on Enzymes in the Laboratory of Physiology at the NIH.Their Section on Enzymes eventually became part of the new Experimental Biology and Medicine Institute and was later renamed the National Institute of Arthritis and Metabolic Diseases.
During World War II, Horecker left Chicago and got a job at the National Institutes of Health (NIH) in Frederick S.
They are currently declining around the world, largely due to the effects of climate change and local anthropogenic issues.
Temperature stress in particular has been associated with significant coral mortality over the last 30 years due to adverse effects on the relationship between reef-building corals and their algal endosymbionts from the genus Symbiodinium.
Joined by Horecker's first postdoctoral student, J. Seegmiller, they worked out a new method for the preparation of glucose 6-phosphate and 6-phosphogluconate, both of which were not yet commercially available.
As reported in the (JBC) Classic reprinted here, they purified 6-phosphogluconate dehydrogenase from brewer's yeast (1), and by coupling the reduction of TPN to its reoxidation by pyruvate in the presence of lactic dehydrogenase, they were able to show that the first product of 6-phosphogluconate oxidation, in addition to carbon dioxide, was ribulose 5-phosphte.
His total contributions included the discovery of three new sugar phosphate esters, ribulose 5-phosphate, sedoheptulose 7-phosphate, and erythrose 4-phosphate, and three new enzymes, transketolase, transaldolase, and pentose-phosphate 3-epimerase.
The outline of the complete pentose phosphate cycle was published in 1955 (2).
Horecker also served as president of the American Society of Biological Chemists (now the American Society for Biochemistry and Molecular Biology) in 1968.
To examine how Symbiodinium physiology may be contributing to these observed differences, eight Symbiodinium cultures, or Symbiodinium types, were exposed to elevated temperature stress, and several parameters that impact the bleaching response were measured.
These included the production of reactive oxygen species (ROS), the activity of antioxidants responsible for scavenging ROS, oxygen uptake rates (V́́o2) as a measure of metabolism, growth rates, and loss of the photosynthetic chlorophyll a (Chl a) pigment.
193, 383–396) Bernard Leonard Horecker (1914) began his training in enzymology in 1936 as a graduate student at the University of Chicago in the laboratory of T. However, when Erwin Hass arrived from Otto Warburg's laboratory he asked Horecker to join him in the search for an enzyme that would catalyze the reduction of cytochrome by reduced NADP.
