A Diffusion-Based Approach to Geminate Recombination of Heme Proteins with Small Ligands [PDF]

open access: yes, 2002
A model of postphotodissociative monomolecular (geminate) recombination of heme proteins with small ligands (NO, O2 or CO) is represented. The non-exponential decay with time for the probability to find a heme in unbound state is interpreted in terms of ...

Functional selectivity of GPCR-directed drug action through location bias. [PDF]

open access: yes, 2017
G-protein-coupled receptors (GPCRs) are increasingly recognized to operate from intracellular membranes as well as the plasma membrane. The β 2 -adrenergic GPCR can activate G s -linked cyclic AMP (G s -cAMP) signaling from endosomes.

Structural and energetic effects of A2A adenosine receptor mutations on agonist and antagonist binding.

open access: yesPLoS ONE, 2014
To predict structural and energetic effects of point mutations on ligand binding is of considerable interest in biochemistry and pharmacology. This is not only useful in connection with site-directed mutagenesis experiments, but could also allow ...

Ligand Modulation of Lateral Segregation of a G-Protein-Coupled Receptor into Lipid Microdomains in Sphingomyelin/Phosphatidylcholine Solid-Supported Bilayers [PDF]

open access: yesBiochemistry, 2005
A growing body of evidence supports the idea that the plasma membrane bilayer is characterized by a laterally inhomogeneous mixture of lipids, having an organized structure in which lipid molecules segregate into small domains or patches. Such microdomains are characterized by high contents of sphingolipids that form thicker liquid-ordered regions that

4-[(E)-2-(1-Pyrenyl)Vinyl]Pyridine Complexes: How to Modulate the Toxicity of Heavy Metal Ions to Target Microbial Infections

open access: yesMolecules
Pyrene derivatives are regularly proposed for use in biochemistry as dyes due to their photochemical characteristics. Their antibacterial properties are, however, much less well understood. New complexes based on 4-[(E)-2-(1-pyrenyl)vinyl]pyridine (PyPe)
