Selective 1Halpha NMR methods to reveal functionally relevant proline cis/trans isomers in IDPs: characterization of minor forms, effects of phosphorylation and occurrence in proteome
Selective 1Halpha NMR methods to reveal functionally relevant proline cis/trans isomers in IDPs: characterization of minor forms, effects of phosphorylation and occurrence in proteome
Identification of proline cis/trans isomers appearing in several regulatory mechanisms of proteins and characterization of minor species present due to the conformational heterogeneity in IDPs is highly important. To obtain residue level information on these mobile systems we introduce two 1 H ? -detected, proline selective, real-time homodecoupled NMR experiments and analyze the proline abundant transactivation domain of p53. The measurements are sensitive enough to identify minor conformers...
