TL;DR: The condensation reactions occurring between vanadate and a number of amino acids and simple peptides have been studied by 51V nuclear magnetic resonance (NMR) signals as discussed by the authors.
Abstract: The condensation reactions occurring between vanadate and a number of amino acids and simple peptides have been studied by 51V nuclear magnetic resonance. Vanadate and ligand stoichiometry has been established for the complexes formed and their formation constants determined. The amino acids were all found to undergo rather weak interactions with vanadate and in general provided two products with 51V chemical shifts near −545 and −555 ppm. The peptides also gave minor products with NMR signals occurring with that of vanadate itself. However, in this case, the major products occur at approximately −510 ppm. These latter complexes are monovanadate, monoligand complexes which require the terminal amino, the carboxylate groups and an unsubstituted nitrogen in the peptide linkage in order for product formation to occur. Sidechains promote product formation, apparently by favouring a more readily complexed peptide conformation. Formation constants vary from about 20 to 50 M−1 depending on the sidechain. The car...

TL;DR: A cell line originating from the fetal rat aorta has been studied with respect to 45Ca2+ uptake, showing an initial rapid uptake followed by a slow linear phase; both the initial rate and the maximum uptake were increased in the presence of 55 mM potassium chloride.

TL;DR: The combined effects of the NH2-terminal deletion and the Glu233substitutions are synergistic rather than additive, consistent with an interaction between the NH4-M5 cytoplasmic loop bearing the nucleotide binding and phosphorylation sites, and possibly the large M2-M3 cytopLasmic loops.
