Effects of two stabilizing substitutions, D137L and G126R, in the middle part of α-tropomyosin on the domain structure of its molecule.

Abstract

We applied differential scanning calorimetry (DSC) to investigate the effects of substitutions D137L and G126R (i.e. replacement of conserved non-canonical residues Asp137 and Gly126 by canonical ones) in the middle part of tropomyosin (Tm), as well as the combined one, D137L/G126R, on the thermal unfolding of Tm. Special approaches (e.g. combination of DSC… (More)
