Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Protein Dynamics and its Correlation to Protein Activity and Stability [PDF]

open access: yes, 2009
The aim of this thesis is to investigate the role of fast protein dynamics (picosecond timescale) in enzyme activity and stability, and specifically to test the hypothesis that enzyme activity and stability are inversely related by their internal ...

Genetic variations affecting ACE2 protein stability in minority populations

open access: yesFrontiers in Medicine, 2022
While worldwide efforts for improving COVID-19 vaccines are currently considered a top priority, the role of the genetic variants responsible for virus receptor protein stability is less studied.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

A Stability Switch for Proteins

open access: yesChemistry & Biology, 2006
A paper published in the September 8 issue of Cell describes a generally applicable approach for chemical control of protein stability, with potential for broad use in chemical genetics.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Stability of protein-based drugs: Herceptin a case study [PDF]

open access: yes, 2016
There is a lack of stability data for in-use parenteral drugs. Manufacturers state a shelf-life of 24 hours for infusions based on microbiological contamination.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Feasibility of microfluidic routes to monitor protein stability as a tool for bioprocessing [PDF]

open access: yes, 2010
During the bioprocessing of therapeutics, proteins may become damaged leading to modifications and changes in stability. This may, as a consequence, cause serious and potentially fatal side effects when administered to patients making damage ...

Hsp90 Breaks the Deadlock of the Hsp70 Chaperone System [PDF]

open access: yes, 2018
Protein folding in the cell requires ATP-driven chaperone machines such as the conserved Hsp70 and Hsp90. It is enigmatic how these machines fold proteins.
