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 ...
Decay characteristics of 84Se
(Elsevier, 1968-11)
The nuclide 84Se has been identified among the fission products of 235U. The selenium fraction was obtained by solvent extraction from HBr into 2,6-dimethyl-4-heptanone. The radiations were studied by [beta]- and [gamma]-ray ...
New chain conformations of poly(glutamic acid) and polylysine
(Wiley Subscription Services, Inc., A Wiley Company, 1968-09)
No Abstract.
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 ...
Modular solid-state unit for electrochemical studies
(Elsevier, 1968)
A relatively inexpensive unit based upon solid-state operational amplifiers is described; its modular design makes it an extremely versatile instrument for many electrochemical techniques, e.g., normal direct current ...
Formation of Dg-1-amino-2-propanol by a highly purified enzyme from Escherichia coli
(Elsevier, 1968-05-14)
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.
