Dynamic fluorescence depolarization: a powerful tool to explore protein folding on the ribosome

SA Weinreis, JP Ellis, S Cavagnero - Methods, 2010 - Elsevier
Protein folding is a fundamental biological process of great significance for cell function and
life-related processes. Surprisingly, very little is presently known about how proteins fold in …

Complementary Role of Co- and Post-Translational Events in De Novo Protein Biogenesis

RM Addabbo, MD Dalphin, MF Mecha… - The Journal of …, 2020 - ACS Publications
The relation between co-and post-translational protein folding and aggregation in the cell is
poorly understood. Here, we employ a combination of fluorescence anisotropy decays in the …

Kinetic trapping of folded proteins relative to aggregates under physiologically relevant conditions

AE Varela, JF Lang, Y Wu, MD Dalphin… - The Journal of …, 2018 - ACS Publications
Anfinsen's thermodynamic hypothesis does not explicitly take into account the possibility of
protein aggregation. Here, we introduce a cyclic-perturbation approach to prove that not only …

[HTML][HTML] Topology is the principal determinant in the folding of a complex all-alpha Greek key death domain from human FADD

A Steward, GS McDowell, J Clarke - Journal of molecular biology, 2009 - Elsevier
In order to elucidate the relative importance of secondary structure and topology in
determining folding mechanism, we have carried out a phi-value analysis of the death …

EPIC-and CHANCE-HSQC: two 15N-photo-CIDNP-enhanced pulse sequences for the sensitive detection of solvent-exposed tryptophan

A Sekhar, S Cavagnero - Journal of Magnetic Resonance, 2009 - Elsevier
Photochemically induced dynamic nuclear polarization (photo-CIDNP) of nuclei other than
1H offers a tremendous potential for sensitivity enhancement in liquid state NMR under mild …

Nascent chains derived from a foldable protein sequence interact with specific ribosomal surface sites near the exit tunnel

MM Masse, V Guzman-Luna, AE Varela… - Scientific Reports, 2024 - nature.com
In order to become bioactive, proteins must be translated and protected from aggregation
during biosynthesis. The ribosome and molecular chaperones play a key role in this …

Replacement of the distal histidine reveals a noncanonical heme binding site in a 2-on-2 hemoglobin

DB Nye, JTJ Lecomte - Biochemistry, 2018 - ACS Publications
Heme ligation in hemoglobin is typically assumed by the “proximal” histidine. Hydrophobic
contacts, ionic interactions, and the ligation bond secure the heme between two α-helices …

1H Photo-CIDNP Enhancements in Heteronuclear Correlation NMR Spectroscopy

A Sekhar, S Cavagnero - The Journal of Physical Chemistry B, 2009 - ACS Publications
Photochemically induced dynamic nuclear polarization (photo-CIDNP) is usually employed
as a probe of solvent exposure in biomolecular NMR. The potential of the photo-CIDNP …

Production of ribosome-released nascent proteins with optimal physical properties

DR Ziehr, JP Ellis, PH Culviner… - Analytical …, 2010 - ACS Publications
The growing interest in protein folding under physiologically relevant conditions has
prompted investigations requiring direct comparisons between ribosome-bound and …

Sub-millisecond chain collapse of the Escherichia coli globin ApoHmpH

L Zhu, N Kurt, J Choi, LJ Lapidus… - The Journal of Physical …, 2013 - ACS Publications
Myoglobins are ubiquitous proteins that play a seminal role in oxygen storage, transport,
and NO metabolism. The folding mechanism of apomyoglobins from different species has …
