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 ...
Inhibition of protein synthesis in cell-free systems by homocitrullylamino adenosine
(Elsevier, 1963)
Homocitrullylamino adenosine inhibits the incorporation of [14C]amino acids into a hot acid-insoluble form in cell-free systems derived from Escherichia coli and rat liver. The concentration necessary for one-half maximal ...
Solubilization of water by dialkyl sodium sulfosuccinates in hydrocarbon solutions
(Elsevier, 1969-01)
The apparent solubilization of water in hydrocarbon solvents by the addition of 0.1% to 2.0% w/w di-(2-ethylhexyl) sodium sulfosuccinate (AOT) has been studied. In n-octane and n-decane, transitions of clear-turbid-clear-turbid ...
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 ...
Infrared spectra and assignments for polyvinyl chloride and deuterated analogs
(John Wiley & Sons, Inc., 1963-08)
Deuterated analogs of polyvinyl chloride (PVC) have been prepared and their infrared spectra analyzed as an aid to the more detailed assignment of bands in the spectrum of PVC. The following deuterated polymers were studied: ...
Circular dichroism of the “random” polypeptide chain
(Wiley Subscription Services, Inc., A Wiley Company, 1969-09)
The circular dichroism (CD) spectrum of an unordered polypeptide chain does not correspond, as has been assumed heretofore, to that of a charged chain such as poly- L -glutamic acid or poly- L -lysine. The latter have been ...

Studies of the in vitro and in vivo effects of conjugated steroids and carboxylic acids on hepatic tyrosine transaminase in the rat
(Elsevier, 1967-11-14)
1. 1. Tyrosine transaminase (-tyrosine:2-oxoglutarate aminotransferase, EC 2.6.1.5) activity was lost rapidly in fresh rat-liver homogenates (pH 6.9), that were incubated at 38[deg]. The inactivation was paralled by the ...
Radiochemical separation of strontium by amalgam exchange
(Elsevier, 1963-07)
The radiochemical separation of strontium by an amalgam-exchange technique has been critically evaluated with a saturated aqueous solution of potassium chloride as an exchange medium. With an optimised procedure strontium ...
