Properties of yeast pyruvate decarboxylase and their modification by proteolytic enzymes : II. Selective alteration by yeast proteases
(Elsevier, 1968)
Pyruvate decarboxylase has been shown to be more heat labile in extracts of a mutant strain than in extracts of the parent yeast strain. Mutant extracts were found to contain higher levels of proteolytic enzymes than ...
Isolation and reactions of a phosphorylated form of phosphoryl transferase from beef heart mitochondria
(Elsevier, 1968-06)
Phosphoryl transferase, a mitochondrial protein which increases the phosphorylative capacity of poorly phosphorylating submitochondrial particles and catalyzes an ATP-ADP exchange reaction, is phosphorylated during oxidation ...
Solution properties and structure of brain proteolipids
(Wiley Subscription Services, Inc., A Wiley Company, 1968-07)
Bovine white matter proteolipids have been studied by several physical methods and have been found to exist as micelles in 2 : 1 (v/v) chloroform–methanol solution. The data would indicate the existence of a critical micelle ...
Protein-Carbohydrate interaction : VII. Physical and chemical studies on concanavalin A, the hemagglutinin of the jack bean
(Elsevier, 1968)
Concanavalin A yielded a monodiperse pattern in the analytical ultracentrifuge in the pH range 2-5. The sedimentation coefficient, so20,w in pH 5 acetate buffer containing 0.1 NaCl (total [Gamma]/2 = 0.20) was 4S. At pH ...
Transport of amino acids into the estrogen-primed uterus I. General characteristics of the uptake in vitro
(Elsevier, 1968-01-03)
The uptake of free amino acids by the immature rat uterus has been studied in vitro. 1. 1. The uptake of the model amino acid, [alpha]-aminoisobutyric acid, showed properties of active transport. It was saturable; it ...
Sensitive amperometric titration of o-phenylenediamine employing catalyticelectrode reaction end-point detection
(Elsevier, 1968-03)
The catalytic prewave of the Ni-opda system has been used for a sensitive amperometric detection of the end-point of the opda titration. Au(III) was chosen as titrant from a large group of possible oxidants, because of its ...
Purification of cerebroside galactosidase from rat brain
(Elsevier, 1968-05-01)
A method is described for the preparation of a [beta]-galactosidase which acts on the brain lipid, ceramide galactoside. The enzyme is obtained from particles that sediment between 1000-13000 x g from rat brains and is ...
A proton magnetic resonance study of the system: Di-(2-Ethylhexyl) Sodium Sulfosuccinate--water-n-Octane
(Elsevier, 1968-09)
Proton magnetic resonance (pmr) has proved to be a useful technique for following the behavior of water in the complex equilibria produced when water is added to solutions of di-(2-ethylhexyl)sodium sulfosuccinate, (Aerosol ...
