NMR assignments of the N-terminal domain of Nephila clavipes spidroin 1.

The building blocks of spider dragline silk are two fibrous proteins secreted from the major ampullate gland named spidroins 1 and 2 (MaSp1, MaSp2). These proteins consist of a large central domain composed of approximately 100 tandem copies of a 35-40 amino acid repeat sequence. Non-repetitive N and C-terminal domains, of which the C-terminal domain has been implicated to transition from soluble and insoluble states during spinning, flank the repetitive core. The N-terminal domain until recently has been largely unknown due to difficulties in cloning and expression. Here, we report nearly complete assignment for all (1)H, (13)C, and (15)N resonances in the 14 kDa N-terminal domain of major ampullate spidroin 1 (MaSp1-N) of the golden orb-web spider Nephila clavipes.

Extensive de novo solid-state NMR assignments of the 33 kDa C-terminal domain of the Ure2 prion Extensive de novo solid-state NMR assignments of the 33 kDa C-terminal domain of the Ure2 prion Abstract We present the de novo resonance assignments for the crystalline 33 kDa C-terminal domain of the Ure2 prion using an optimized set of five 3D solid-state NMR spectra. We obtained, using a single uniformly 13C, 15N labeled protein sample, sequential chemical-shift information for 74% of the N, CÎ±, CÎ² triples, and for 80% of further side-chain resonances for these spin systems. We describe the procedures and protocols devised, and discuss possibilities and limitations of the...	nmrlearner	Journal club	0	08-04-2011 01:14 AM
