Functional and regulatory roles of fold-switching proteins

AK Kim, LL Porter - Structure, 2021 - cell.com
Fold-switching proteins respond to cellular stimuli by remodeling their secondary structures
and changing their functions. Whereas several previous reviews have focused on various …

Distinguishing features of fold‐switching proteins

D Chakravarty, JW Schafer, LL Porter - Protein Science, 2023 - Wiley Online Library

[HTML][HTML] Design and discovery of metamorphic proteins

AF Dishman, BF Volkman - Current opinion in structural biology, 2022 - Elsevier
Metamorphic proteins are single amino acid sequences that reversibly interconvert between
multiple, dramatically different native structures, often with distinct functions. Since the …

Reframing the protein folding problem: Entropy as organizer

GD Rose - Biochemistry, 2021 - ACS Publications
It has been a long-standing conviction that a protein's native fold is selected from a vast
number of conformers by the optimal constellation of enthalpically favorable interactions. In …

Fluid protein fold space and its implications

LL Porter - Bioessays, 2023 - Wiley Online Library
Fold‐switching proteins, which remodel their secondary and tertiary structures in response
to cellular stimuli, suggest a new view of protein fold space. For decades, experimental …

Structure of the hydrophobic core determines the 3D protein structure—verification by single mutation proteins

M Banach, P Fabian, K Stapor, L Konieczny… - Biomolecules, 2020 - mdpi.com
Four de novo proteins differing in single mutation positions, with a chain length of 56 amino
acids, represent diverse 3D structures: monomeric 3α and 4β+ α folds. The reason for this …
