WebSep 11, 2007 · Dynamics of large-amplitude conformational motions in proteins are complex and less understood, although these processes are intimately associated with structure, folding, stability, and function of proteins. Here, we use a large set of spectra obtained by cross-relaxation suppressed exchange NMR spectroscopy (EXSY) to study the 180° … WebMay 5, 2010 · The folding energy landscape of cytochrome c is particularly interesting because of the effects of its large, covalently bound heme cofactor. 1,2 In fact, the heme is one of the major reasons that cytochrome c has been studied for decades as a model system for protein folding and dynamics. 3–8 The heme molecule serves as a …
WebThe HX MS experiments measured Cyt c folding at a protein concentration much lower (1–4 µM) than the 1 mM concentration used in the earlier NMR work. All Cyt c molecules fold their terminal helices (blue) in the same early ∼10-ms step, showing that the heterogeneity previously seen was due to aggregation during folding at the high protein ... WebDec 21, 2011 · Interactions of cytochrome c (cyt c) with cardiolipin (CL) are important for both electron transfer and apoptotic functions of this protein. A sluggish peroxidase in its native state, when bound to CL, cyt c catalyzes CL peroxidation, which contributes to the protein apoptotic release.
