Conformational Dependence of a Protein Kinase Phosphate Transfer Reaction
, 2004 Atomic motions and energetics for a phosphate transfer reaction catalyzed by the cAMP-dependent protein kinase (PKA) are calculated by plane-wave density functional theory, starting from structures of proteins crystallized in both the reactant ...

The social network (of protein conformations) [PDF]
Proceedings of the National Academy of Sciences, 2011 Proteins possess thousands of degrees of freedom, and yet, they can rapidly and reliably find their way into well-defined folded configurations (1). In the cell, these folded proteins carry out highly specific motions critical to cargo transport and force transduction, energy generation, and catalysis.

On the vibrational free energy of hydrated proteins [PDF]
Phys. Biol. 2021, vol.18 (3), 036003, 2020 When the hydration shell of a protein is filled with at least 0.6 gram of water per gram of protein, a significant anti-correlation between the vibrational free energy and the potential energy of energy-minimized conformers is observed. This means that low potential energy, well-hydrated, protein conformers tend to be more rigid than high-energy ones ...

Dendritic cells steering antigen and leukocyte traffic in lymph nodes
FEBS Letters, EarlyView.Dendritic cells are key players in the activation of T cells and their commitment to effector function. In this In a Nutshell Review, we will discuss how dendritic cells guide the trafficking of antigen and leukocytes in the lymph node, thus influencing T‐cell activation processes. Dendritic cells (DCs) play a central role in initiating and shaping the

Epitope-Specific Serological Assays for RSV: Conformation Matters
Vaccines, 2019 Respiratory syncytial virus (RSV) causes substantial morbidity and mortality in children and older adults. An effective vaccine must elicit neutralizing antibodies targeting the RSV fusion (F) protein, which exists in two major conformations, pre-fusion (

p97 Disease Mutations Modulate Nucleotide-Induced Conformation to Alter Protein-Protein Interactions. [PDF]
, 2016 The AAA+ ATPase p97/VCP adopts at least three conformations that depend on the binding of ADP and ATP and alter the orientation of the N-terminal protein-protein interaction (PPI) domain into up and down conformations.

Proton-coupled sugar transport in the prototypical major facilitator superfamily protein XylE. [PDF]
, 2014 The major facilitator superfamily (MFS) is the largest collection of structurally related membrane proteins that transport a wide array of substrates.

Conformational footprints [PDF]
Nature Chemical Biology, 2016 The mechanisms by which proteins evolve new functions can be slow and mysterious. Comprehensive structural analysis of enzyme variants reveal how gradual enrichments of pre-existing populations with the right productive dynamics for new functions can accomplish this aim.

FEBS Letters, EarlyView.In vivo IL‐10 produced by tissue‐resident tolDC is involved in maintaining/inducing tolerance. Depending on the agent used for ex vivo tolDC generation, cells acquire common features but prime T cells towards anergy, FOXP3+ Tregs, or Tr1 cells according to the levels of IL‐10 produced. Ex vivo‐induced tolDC were administered to patients to re‐establish/
