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.
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)
Effects of non-metabolizable analogs on the distribution of amino acids in the rat
(Elsevier, 1968-03-01)
The injection into the normal or adrenalectomized rat of [alpha]-aminoisobutyric acid caused the loss from the liver within 2 h of 1/3 to 2/3 of its normal content of the various neutral amino acids. At the same time a ...
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 ...
