Crosslinking, salt-induced aging, and secondary structure formation in Peptide-containing coacervates inspired by spider silk

Communications Chemistry
Spider silks are exceptional biomaterials: biocompatible, biodegradable, and with remarkable mechanical properties. Unfortunately, attempts to replicate them tend to fail due to the difficulty of synthesizing the proteins that constitute them, and to an ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Symmetry-based pulse sequences in solid-state NMR and applications to biological systems [PDF]

, 2003
We present some applications of solid-state nuclear magnetic resonance to model compounds and biological systems. We highlight a class of pulse sequences that are designed based on symmetry properties of the internal spin interactions. Examples are given

Dynamic nuclear polarization and spin-diffusion in non-conducting solids

, 2008
There has been much renewed interest in dynamic nuclear polarization (DNP), particularly in the context of solid state biomolecular NMR and more recently dissolution DNP techniques for liquids.

NMR multiple quantum coherences in quasi-one-dimensional spin systems: Comparison with ideal spin-chain dynamics [PDF]

, 2009
The 19F spins in a crystal of fluorapatite have often been used to experimentally approximate a one-dimensional spin system. Under suitable multi-pulse control, the nuclear spin dynamics may be modeled to first approximation by a double-quantum one ...
