Structural Characteristics of Stable Folding Intermediates of Yeast Iso-1-Cytochrome-c
Cytochrome-c (cyt-c) is an electron transport protein, and it is present throughout the evolution. More than 280 sequences have been reported in the protein sequence database (www.uniprot.org). Though sequentially diverse, cyt-c has essentially retained its tertiary structure or fold. Thus a vast data set of varied sequences with retention of similar structure and fun...

متن کاملDenaturation and renaturation of self-assembled yeast iso-1-cytochrome c on Au.
We have made surface plasmon resonance (SPR) measurements of yeast iso-1-cytochrome c (Cyt c) on a gold surface. Angle-resolved SPR curves are recorded as a function of urea concentration before and after self-assembly of the Cyt c. Exposure to a urea solution causes denaturation of Cyt c, which shifts the minimum in the SPR curve to a larger angle and decreases the signal amplitude. The Gibbs ...
متن کاملThe mutational alteration of the primary structure of yeast iso-1-cytochrome c.
A benzidine-HzOz staining procedure and genetic tests were used for the detection of cytochrome c-deficient mutants of the cyl, cy2, cy3, cy4, and cy6 loci. The chromosomal gene, CY1, was shown to encode the primary structure of iso-l-cytochrome c from bakers’ yeast. Sixteen cyl mutants were isolated after examining over 1 million colonies. These cyl mutants could be categorized as follows: (a)...
متن کاملConformational Toggling of Yeast Iso-1-Cytochrome c in the Oxidized and Reduced States
To convert cyt c into a peroxidase-like metalloenzyme, the P71H mutant was designed to introduce a distal histidine. Unexpectedly, its peroxidase activity was found even lower than that of the native, and that the axial ligation of heme iron was changed to His71/His18 in the oxidized state, while to Met80/His18 in the reduced state, characterized by UV-visible, circular dichroism, and resonance...
