Local conformational transition of Hydrogenobacter thermophilus cytochrome c552 relevant to its redox potential.

In order to elucidate the molecular mechanisms responsible for the apparent nonlinear behavior of the temperature dependence of the redox potential of Hydrogenobacter thermophilus cytochrome c552 [Takahashi, Y., Sasaki, H., Takayama, S.

Further enhancement of the thermostability of Hydrogenobacter thermophilus cytochrome c552.

Thermophile Hydrogenobacter thermophilus cytochrome c(552) (HT) is a stable protein with denaturation temperatures (T(m)) of 109.8 and 129.7 degrees C for the oxidized and reduced forms, respectively [Uchiyama, S.
