Protein-carbohydrate interaction : III. Agar gel-diffusion studies on the interaction of concanavalin A, a lectin isolated from jack bean, with polysaccharides
(Elsevier, 1965-08)
Concanavalin A, a protein isolated from the jack bean (Canavalia ensiformis), has previously been shown to form a precipitate with glycogen and yeast mannan, and more recently with dextrans and amylopectin. Double-diffusion ...
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 ...
Characterization of a mutant human erythrocyte carbonic anhydrase: Carbonic anhydrase IcGuam: The amino acid substitution and carboxylesterase and hydratase activities
(Elsevier, 1966-11)
Evidence is presented which indicates that an arginine residue has substituted for a glycine residue in the abnormal human erythrocyte carbonic anhydrase, CA IcGuam. The ratio of the amount of mutant to normal enzyme ...
Physicochemical and immunochemical studies on the reaction of bovine serum albumin with p,p'-difluoro-m,m'-dinitrodiphenylsulfone
(Elsevier, 1963-02)
Bovine serum albumin (BSA) was reacted with the bifunctional reagent p,p'-difluoro-m,m'-dinitrodiphenylsulfone (FNPS) under varying conditions. While intramolecular cross linkages involving the lysine and tyrosine residues ...
Mixing device for generating simple chromatographic gradients
(Elsevier, 1965-10)
A linear gradient device consisting of two concentric reservoirs of equal cross-sectional area, in which the initial and limiting eluent solutions are maintained in hydrostatic equilibrium, may be constructed from several ...
A quantitative automated technique for the determination of diazotizable imidazole compounds in biological material
(Elsevier, 1966)
A quantitative automated apparatus is described for the simultaneous determination of a number of diazotizable imidazole compounds in the same sample of biological material. Its use in the analysis of urine, plasma and ...
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 ...
