Assignment of 15N chemical shifts and 15N relaxation measurements for oxidized and reduced iso-1-cytochrome c.


A protocol for complete isotopic labeling of iso-1-cytochrome c from the eukaryote Saccharomyces cerevisiae is reported. Assignments are reported for the vast majority of the 15N amide resonances in both oxidized and reduced states. 15N heteronuclear relaxation experiments were collected to study the picosecond-nanosecond backbone dynamics of this protein… (More)
