When fast is better: protein folding fundamentals and mechanisms from ultrafast approaches

V Munoz, M Cerminara - Biochemical Journal, 2016 - portlandpress.com
Protein folding research stalled for decades because conventional experiments indicated
that proteins fold slowly and in single strokes, whereas theory predicted a complex interplay …

Limited cooperativity in protein folding

V Munoz, LA Campos, M Sadqi - Current Opinion in Structural Biology, 2016 - Elsevier
Theory and simulations predict that the structural concert of protein folding reactions is
relatively low. Experimentally, folding cooperativity has been difficult to study, but in recent …

Weak protein–protein interactions in live cells are quantified by cell-volume modulation

S Sukenik, P Ren, M Gruebele - Proceedings of the …, 2017 - National Acad Sciences
Weakly bound protein complexes play a crucial role in metabolic, regulatory, and signaling
pathways, due in part to the high tunability of their bound and unbound populations. This …

Kinetic model of GPCR-G protein interactions reveals allokairic modulation of signaling

KJ Culhane, TM Gupte, I Madhugiri, CJ Gadgil… - Nature …, 2022 - nature.com
Established models of ternary complex formation between hormone, G protein coupled
receptor (GPCR), and G protein assume that all interactions occur under equilibrium …

Domain topology, stability, and translation speed determine mechanical force generation on the ribosome

SE Leininger, F Trovato, DA Nissley… - Proceedings of the …, 2019 - National Acad Sciences
The concomitant folding of a nascent protein domain with its synthesis can generate
mechanical forces that act on the ribosome and alter translation speed. Such changes in …

In vivo translation rates can substantially delay the cotranslational folding of the Escherichia coli cytosolic proteome

P Ciryam, RI Morimoto… - Proceedings of the …, 2013 - National Acad Sciences
A question of fundamental importance concerning protein folding in vivo is whether the
kinetics of translation or the thermodynamics of the ribosome nascent chain (RNC) complex …

Modern analysis of protein folding by differential scanning calorimetry

B Ibarra-Molero, AN Naganathan… - Methods in …, 2016 - Elsevier
Differential scanning calorimetry (DSC) is a very powerful tool for investigating protein
folding and stability because its experimental output reflects the energetics of all …

Prediction of variable translation rate effects on cotranslational protein folding

EP O'brien, M Vendruscolo, CM Dobson - Nature communications, 2012 - nature.com
The concomitant folding of a protein with its synthesis on the ribosome is influenced by a
number of different timescales including the translation rate. Here we present a kinetic …

Kinetic modelling indicates that fast-translating codons can coordinate cotranslational protein folding by avoiding misfolded intermediates

EP O'Brien, M Vendruscolo, CM Dobson - Nature communications, 2014 - nature.com
It has been observed for several proteins that slowing down the rate at which individual
codons are translated can increase their probability of cotranslational protein folding, while …

New scenarios of protein folding can occur on the ribosome

EP O'Brien, J Christodoulou… - Journal of the …, 2011 - ACS Publications
Identifying and understanding the differences between protein folding in bulk solution and in
the cell is a crucial challenge facing biology. Using Langevin dynamics, we have simulated …
