Background: Testing the hypoxic ventilatory response (HVR) at low-altitude helps to detect those who do not hyperventilate appropriately in hypoxia but might not necessarily predict the HVR and the risk to develop acute mountain sickness (AMS) at high alti ...
Protein drugs have great potential as targeted therapies, yet their application suffers from several drawbacks, such as instability, short half-life, and adverse immune responses. Thus, protein delivery approaches based on stimuli-responsive nanocarriers c ...
Proteins are dynamic macromolecules, which accomplish biological function driven by long-range interactions and global motions. While their biological function is often clear, little is known about the collective interactions which make these systems real ...
Understanding the interplay between protein function and dynamics is currently one of the fundamental challenges of physical biology. Recently, a method using variable temperature solid-state nuclear magnetic resonance relaxation measurements has been prop ...
Hb I (HbI) is an invertebrate monomeric hemeprotein from Lucina pectinata that contains 142 amino acid residues. The HbI heme pocket structural compn. shows an arrangement of phenylalanyl residues (Phe (29), Phe (43) and Phe (68)) that has not been obsd. i ...
We carry out a first-principles atomistic study of the electronic mechanisms of ligand binding and discrimination in the myoglobin protein. Electronic correlation effects are taken into account using one of the most advanced methods currently available, na ...
Genetically encoded fluorescent sensor proteins offer the possibility to probe the concentration of key metabolites in living cells. The approaches currently used to generate such fluorescent sensor proteins lack generality, as they require a protein that ...
A mass spectrometry-based assay combining the specificity of selected reaction monitoring and the protein ion activation capabilities of electron transfer dissociation was developed and employed for the rapid identification of hemoglobin variants from whol ...
The dynamics of the ferric CN complexes of the heme proteins Myoglobin and Hb I from the clam Lucina pectinata upon Soret band excitation is monitored using IR and broad band visible pump-probe spectroscopy. The transient response in the UV-vis spectral re ...
We introduce here a new class of BODIPY-based Ca2+ indicators which can be derivatized with biological ligands that permit the localization of the indicators in living cells. The underivatized BODIPY-based Ca2+ indicator (BOCA-1) shows a 250-fold increase ...
