Traditionally known as a toxic gas, hydrogen sulfide (H 2 S) is now recognized as an
important biological molecule involved in numerous physiological functions. Like nitric oxide …

In this review, voltage-gated proton channels are considered from a mainly teleological
perspective. Why do proton channels exist? What good are they? Why did they go to such …

The p K a values and charge states of ionizable residues in polypeptides and proteins are
frequently determined via NMR-monitored pH titrations. To aid the interpretation of the …

The histidine imidazole side chain plays a critical role in protein function and stability. Its
importance for catalysis is underscored by the fact that histidines are localized to active sites …

Nanoparticles in biological media form dynamic entities as a result of competitive adsorption
of proteins on nanoparticle surfaces called protein coronas. The protein affinity toward …

Histidine is an important natural amino acid, involved in many relevant biological processes,
which, because of its physical properties, proved difficult to characterize experimentally in its …

Two-dimensional indirectly detected through-space and through-bond 1 H {15 N} solid-state
NMR experiments utilizing fast magic angle spinning (MAS) and homonuclear multipulse 1 …

The interaction of redox-active copper ions with misfolded amyloid β (Aβ) is linked to
production of reactive oxygen species (ROS), which has been associated with oxidative …

It is well known that histidine is involved in many biological functions due to the structural
versatility of its side chain. However, probing the conformational transitions of histidine in …

The human immunodeficiency virus type‐1 (HIV‐1) Tat protein stimulates transcriptional
elongation. Tat is involved in the transcription machinery by binding to the transactivation …
