Proton nuclear magnetic resonance as a probe of differences in structure between the C102T and F82S,C102T variants of iso-1-cytochrome c from the yeast Saccharomyces cerevisiae.

Abstract excerpt

Differences in chemical shifts and in nuclear Overhauser effects between the C102T and F82S,C102T variants of Saccharomyces cerevisiae iso-1-cytochrome c in both the reduced and oxidized forms are reported and analyzed. There is evidence for small conformational differences in both oxidation states of the double variant near position 82. Differences in structure are more evident in the oxidized forms of the...
