Properties of yeast pyruvate decarboxylase and their modification by proteolytic enzymes : I. Stability of decarboxylases from wild-type and mutant strains
(Elsevier, 1968)
High concentrations of inorganic phosphate and ammonium sulfate stabilize yeast pyruvate decarboxylase to heating at 60 [deg] for long periods of time in the presence of TPP and Mg+. When heated at 60 [deg] in phosphate ...
Gas chromatographic separtion of low molecular weight fluorocarbons
(Elsevier, 1968)
Application of gas-solid chromatography techiques to the separation of low molecular weight fluorocarbons incorporates a number of advantages over previous analysis techniques. These advantages include isothermal operation ...
Effects of physostigmine on rat brain acetylcholine, acetylcholinesterase and conditioned pole jumping,
(Elsevier, 1968-03)
The present study was designed to provide evidence that the behavioral effects of physostigmine are related to inhibition of brain acetylcholinesterase (AChE). Adult male Holtzman rats were trained to pole jump to a buzzer ...
Hydrogen ion buffers and enzymatic activity: Myosin B adenosinetriphosphatase
(Elsevier, 1968-10)
The production of hydrogen ions during the hydrolysis of ATP by myosin B and the consequent fall in pH can produce alterations in enzymatic activity directly, or by influencing Ca ion concentrations controlled by metal-chelate ...
Total radiances and equivalent widths of isolated lines with combined Doppler and collision broadened profiles
(Elsevier, 1968-08)
Analytical expressions for total radiances and equivalent widths of isolated spectral lines with combined Doppler and collision broadened profiles are presented for isothermal paths.
The ATP-ADP exchange catalyzed by phosphoryl transferase
(Elsevier, 1968)
Purified phosphoryl transferase catalyzes an ATP-ADP exchange reaction. Evidence is presented which excludes the possibility that the exchange activity of the preparation is due to contaminating adenylate kinase. The rate ...
Neuronal mechanisms of ketamine-induced anesthesia
(Elsevier, 1968-11)
The sites of action of ketamine (CI-581; 2-(0-chlorophenyl)-2-methylamino cyclohexamine HCl) were determined in the central nervous system using electrophysiological techniques in both acute and chronic cat experiments. ...
