(1990)Endocytic vesicles isolated from rabbit reticulocytes contained an intrinsic Ca2+-pump activity that was dependent on ATP, activated by calmodulin and inhibited by vanadate. 45Ca2+ uptake and acidification studies indicated ...

(1996)Nuclear magnetic resonance (NMR) spectroscopy is emerging as a powerful tool for the study of enzyme structure and function. This article discusses the general principles of NMR and the potential information this technique ...

-
(1989)It has been established that early events in lymphocyte activation involve a rise in intracellular Ca++ as well as changes in the flux of other ions. Although a Ca++ channel has been postulated to participate in the early ...
-
(Springer-Verlag, 1989)A59Fe assay was designed to detect an Fe(III) binding capacity in NP-40 solubilized proteins from rabbit reticulocyte endocytic vesicles. The iron binding capacity had an apparent molecular weight as determined by gel ...
-
(1989)The dispersal syndromes of 72 species from the temperate rain forest of Chiloe were analysed and compared with data for other temperate forests in New Zealand and New Jersey, and for dry, moist and wet neotropical forests. ...
-
(Kluwer Academic Publishers-Plenum Publishers, 1988)The olfactory epithelium has the ability to respond to a large number of volatile compounds of small molecular weight. Ultimately, such a property lies on a specialized type of neuron, the olfactory receptor cell. In the ...
-
(1989)In Alzheimer's disease, the most characteristic neuropathological changes are the formation of neurofibrillary tangles (NFT) and neuritic plaques (NP) characterized by the presence of bundles of paired helical filaments ...
-
(American Chemical Society, 1999)Molecular vibrations in ammonia (NH3) and hydrogen sulfide (H2S), and internal rotations in hydrogen peroxide (HOOH), hydrogen thioperoxide (HSOH), hydrogen persulfide (HSSH), and ethylene (C2H4) are studied using ab initio ...
-
(1987)Stands were dominated by broad-leaved evergreen trees and had in common the presence of several species of Myrtaceous trees in their canopies. Structurally, the forests were dominated by different species, although overall ...
-
(1988)The aggregation states of Escherichia coli phosphofructokinase 2 (Pfk-2) and of a mutant enzyme (Pfk-2*) altered in the inhibitory allosteric site for MgATP were measured in the presence and in the absence of substrates ...
-
(Kluwer Academic Publishers, 1988)The regeneration of canopy and subeanopy species in a mid-elevation, primary rain forest in the Coastal Range of Isla de Chiloé (42°30′S), in the cold-temperate region of Chile, was studied by comparing seedling and sapling ...
-
(1987)The inhibitory effects of guanosine 5'-(ᵧ-fluorotriphosphate) [GTP(ᵧF)] on both the polymerization and the colchicine-dependent GTPase activity of calf brain tubulin have been studied. The results demonstrate that this ...
-
(Kluwer Academic Publishers, 1987)Questions of successional pattern and causality have been central concerns in vegetation ecology. In this paper we address the limits of the overextended models of Connell and Slatyer by discussing problems encountered in ...
-
(1986)The light-activated conductance of Limulus ventral photoreceptors was studied using the patch-clamp technique. Channels (40 pS) were observed whose probability of opening was greatly increased by light. In some cells the ...
-
(1987)Pristidactylus volcanensis, a new species from El Volcan, Cordillera de Los Andes, is distinguished by coloration, squamation, measurements, and habitus. -from Authors
-
(1997)The electronic structure of 1T-TiS2 intercalated with lithium is analysed within a molecular approach that uses a finite-size cluster to represent the solid. Electronic descriptors such as the electronic chemical potential, ...
