Computational design of the Fyn SH3 domain with increased stability through optimization of surface charge charge interactions (2007)

Schweiker, Katrina L., Zarrine-Afsar, Arash, Davidson, Alan R., Makhatadze, George I.

Computational design of surface charge–charge interactions has been demonstrated to be an effective way to increase both the thermostability and the stability of proteins. To test the robustness of...

Protein stabilization by specific binding of guanidinium to a functional arginine-binding surface on an SH3 domain (2006)

Zarrine-Afsar, Arash, Mittermaier, Anthony, Kay, Lewis E., Davidson, Alan R.

Guanidinium hydrochloride (GuHCl) at low concentrations significantly stabilizes the Fyn SH3 domain. In this work, we have demonstrated that this stabilizing effect is manifested through a dramatic...

Protein folding: Defining a "standard" set of experimental conditions and a preliminary kinetic data set of two-state proteins (2005)

Maxwell, Karen L., Wildes, David, Zarrine-Afsar, Arash, De Los Rios, Miguel A., Brown, Andrew G., Friel, Claire T., ...

Recent years have seen the publication of both empirical and theoretical relationships predicting the rates with which proteins fold. Our ability to test and refine these relationships has been...

Dramatic acceleration of protein folding by stabilization of a nonnative backbone conformation

Di Nardo, Ariel A., Korzhnev, Dmitry M., Stogios, Peter J., Zarrine-Afsar, Arash, Kay, Lewis E., Davidson, Alan R.

Through a mutagenic investigation of Gly-48, a highly conserved position in the Src homology 3 domain, we have discovered a series of amino acid substitutions that are highly destabilizing, yet...

Conformational instability of the MARK3 UBA domain compromises ubiquitin recognition and promotes interaction with the adjacent kinase domain

Murphy, James M., Korzhnev, Dmitry M., Ceccarelli, Derek F., Briant, Douglas J., Zarrine-Afsar, Arash, Sicheri, Frank, ...

The Par-1/MARK protein kinases play a pivotal role in establishing cellular polarity. This family of kinases contains a unique domain architecture, in which a ubiquitin-associated (UBA) domain is...

Φ-Value analysis of a three-state protein folding pathway by NMR relaxation dispersion spectroscopy

Neudecker, Philipp, Zarrine-Afsar, Arash, Davidson, Alan R., Kay, Lewis E.

Experimental studies of protein folding frequently are consistent with two-state folding kinetics. However, recent NMR relaxation dispersion studies of several fast-folding mutants of the Fyn Src...

Theoretical and experimental demonstration of the importance of specific nonnative interactions in protein folding

Zarrine-Afsar, Arash, Wallin, Stefan, Neculai, A. Mirela, Neudecker, Philipp, Howell, P. Lynne, Davidson, Alan R., ...

Many experimental and theoretical studies have suggested a significant role for nonnative interactions in protein folding pathways, but the energetic contributions of these interactions are not well...
