Dynamics and thermodynamics of protein-ligand interactions [PDF]

open access: yes, 2012
Complex networks of protein-ligand interactions underpin cellular function and communication. Disease can arise from disruption of these networks through the alteration of protein-ligand interaction affinities, for example by protein mutation or ligand ...

Conformational effects on the Circular Dichroism of Human Carbonic Anhydrase II: a multilevel computational study [PDF]

open access: yes, 2013
Circular Dichroism (CD) spectroscopy is a powerful method for investigating conformational changes in proteins and therefore has numerous applications in structural and molecular biology. Here a computational investigation of the CD spectrum of the Human

Molecular dynamics as an approach to study prion protein misfolding and the effect of pathogenic mutations [PDF]

open access: yes, 2011
Computer simulation of protein dynamics offers unique high-resolution information that complements experiment. Using experimentally derived structures of the natively folded prion protein (PrP), physically realistic dynamics and conformational changes ...

Conformational dynamics of the tetracycline-binding aptamer [PDF]

open access: yes, 2011
The conformational dynamics induced by ligand binding to the tetracycline-binding aptamer is monitored via stopped-flow fluorescence spectroscopy and time-correlated single photon counting experiments.

How does conformational flexibility influence key structural features involved in activation of anaplastic lymphoma kinase? [PDF]

open access: yes, 2014
Anaplastic Lymphoma Kinase (ALK) plays a major role in developing tumor processes and therefore has emerged as a validated therapeutic target. Applying atomistic molecular dynamics simulations on the wild type enzyme and the nine most frequently ...

Pressure, motion, and conformational entropy in molecular recognition by proteins

open access: yesBiophysical Reports, 2023
The thermodynamics of molecular recognition by proteins is a central determinant of complex biochemistry. For over a half-century, detailed cryogenic structures have provided deep insight into the energetic contributions to ligand binding by proteins ...

Structural analyses of a constitutively active mutant of exchange protein directly activated by cAMP.

open access: yesPLoS ONE, 2012
Exchange proteins directly activated by cAMP (EPACs) are important allosteric regulators of cAMP-mediated signal transduction pathways. To understand the molecular mechanism of EPAC activation, we have combined site-directed mutagenesis, X-ray ...
