Probing the cooperativity of Thermoplasma acidophilum proteasome core particle gating by NMR spectroscopy [Biophysics and Computational Biology]

Probing the cooperativity of Thermoplasma acidophilum proteasome core particle gating by NMR spectroscopy [Biophysics and Computational Biology]

The 20S proteasome core particle (20S CP) plays an integral role in cellular homeostasis by degrading proteins no longer required for function. The process is, in part, controlled via gating residues localized to the ends of the heptameric barrel-like CP structure that occlude substrate entry pores, preventing unregulated degradation of...

Date: 2014-01-28 Detailed descriptions of atomic coordinates and motions are required for an understanding of protein dynamics and their relation to molecular recognition, catalytic function, and allostery. Historically, NMR relaxation measurements have played a dominant role in the determination of the amplitudes and timescales (picosecond–nanosecond) of bond vector fluctuations, whereas high-resolution X-ray...

Dynamically committed, uncommitted, and quenched states encoded in protein kinase A revealed by NMR spectroscopy [Biophysics and Computational Biology] Dynamically committed, uncommitted, and quenched states encoded in protein kinase A revealed by NMR spectroscopy Masterson, L. R., Shi, L., Metcalfe, E., Gao, J., Taylor, S. S., Veglia, G.... Date: 2011-04-26 Protein kinase A (PKA) is a ubiquitous phosphoryl transferase that mediates hundreds of cell signaling events. During turnover, its catalytic subunit (PKA-C) interconverts between three major conformational states (open, intermediate, and closed) that are dynamically and allosterically activated by nucleotide binding. We show that the structural transitions between these...	nmrlearner	Journal club	0	04-27-2011 04:16 AM
