In situ molecular NMR picture of bioavailable calcium stabilized as amorphous CaCO3 biomineral in crayfish gastroliths [Chemistry]
In situ molecular NMR picture of bioavailable calcium stabilized as amorphous CaCO3 biomineral in crayfish gastroliths
Akiva-Tal, A., Kababya, S., Balazs, Y. S., Glazer, L., Berman, A., Sagi, A., Schmidt, A....
Date: 2011-09-06
Bioavailable calcium is maintained by some crustaceans, in particular freshwater crayfish, by stabilizing amorphous calcium carbonate (ACC) within reservoir organs—gastroliths, readily providing the Ca2+ needed to build a new exoskeleton. Despite the key scientific and biomedical importance of the in situ molecular-level picture of biogenic ACC and its...

Engineering [Ln(DPA)3]3â?? binding sites in proteins: a widely applicable method for tagging proteins with lanthanide ions
Engineering 3â?? binding sites in proteins: a widely applicable method for tagging proteins with lanthanide ions
Abstract Paramagnetic relaxation enhancements from unpaired electrons observed in nuclear magnetic resonance (NMR) spectra present powerful long-range distance restraints. The most frequently used paramagnetic tags, however, are tethered to the protein via disulfide bonds, requiring proteins with single cysteine residues for covalent attachment. Here we present a straightforward strategy to tag proteins site-specifically with paramagnetic lanthanides without a tether and...

Recent advances in segmental isotope labeling of proteins: NMR applications to large proteins and glycoproteins
Recent advances in segmental isotope labeling of proteins: NMR applications to large proteins and glycoproteins
Abstract In the last 15 years substantial advances have been made to place isotope labels in native and glycosylated proteins for NMR studies and structure determination. Key developments include segmental isotope labeling using Native Chemical Ligation, Expressed Protein Ligation and Protein Trans-Splicing. These advances are pushing the size limit of NMR spectroscopy further making larger proteins accessible for this technique. It is just emerging that segmental isotope...

The hydration of amides in helices; a comprehensive picture from molecular dynamics, IR, and NMR.
Related Articles The hydration of amides in helices; a comprehensive picture from molecular dynamics, IR, and NMR.
Protein Sci. 2003 Mar;12(3):520-31
Authors: Walsh ST, Cheng RP, Wright WW, Alonso DO, Daggett V, Vanderkooi JM, DeGrado WF
We examined the hydration of amides of alpha(3)D, a simple, designed three-helix bundle protein. Molecular dynamics calculations show that the amide carbonyls on the surface of the protein tilt away from the...
