Regulatory and structural EF-hand motifs of neuronal calcium sensor-1: Mg 2+ modulates Ca 2+ binding, Ca 2+ -induced conformational changes, and equilibrium unfolding transitions.
Neuronal calcium sensor-1 (NCS-1) is a major modulator of Ca(2+) signaling with a known role in neurotransmitter release. NCS-1 has one cryptic (EF1) and three functional (EF2, EF3, and EF4) EF-handExpand

N-terminal Myristoylation Regulates Calcium-induced Conformational Changes in Neuronal Calcium Sensor-1*
Neuronal calcium sensor-1 (NCS-1), a Ca2+-binding protein, plays an important role in the modulation of neurotransmitter release and phosphatidylinositol signaling pathway. It is known that theExpand

A tracked approach for automated NMR assignments in proteins (TATAPRO)
A novel automated approach for the sequence specific NMR assignments of 1HN, 13Cα, 13Cβ, 13C′/1Hα and 15N spins in proteins, using triple resonance experimental data, is presented. The algorithm,Expand

NMR structure of a parallel-stranded DNA duplex at atomic resolution.
DNA dodecamers have been designed with two cytosines on each end and intervening A and T stretches, such that the oligomers have fully complementary A:T base pairs when aligned in the parallelExpand

Solution structure and calcium-binding properties of M-crystallin, a primordial betagamma-crystallin from archaea.
The lens betagamma-crystallin superfamily has many diverse but topologically related members belonging to various taxa. Based on structural topology, these proteins are considered to beExpand

Selective `unlabeling' of amino acids in fractionally 13C labeled proteins: An approach for stereospecific NMR assignments of CH3 groups in Val and Leu residues
A novel methodology for stereospecific NMR assignments of methyl (CH3) groups of Val and Leu residues in fractionally 13C-labeled proteins is presented. The approach is based on selectiveExpand

NMR characterisation of a triple stranded complex formed by homo-purine and homo-pyrimidine DNA strands at 1:1 molar ratio and acidic pH.
Homo-purine (d-TGAGGAAAGAAGGT) and homo-pyrimidine (d-CTCCTTTCTTCC) oligomers have been designed such that they are complementary in parallel orientation. When mixed in a 1:1 molar ratio, the systemExpand

Energetics and mechanism of Ca2+ displacement by lanthanides in a calcium binding protein.
The displacement of Ca(2+) by trivalent lanthanide ions (Tm(3+)) in a protozoan (Entamoeba histolytica) Ca(2+) binding protein has been studied by NMR and isothermal calorimetry (ITC). The studyExpand
