Conclusion

Trascrizione

Ion mobility-mass spectrometry, or IM-MS, identify the various products ions from the pH-dependent redox and methyl binding reaction of peptides. With the molecular modeling of their tertiary structure, metal correlation can be determined. IM-MS c

Riepilogo

Ion mobility-mass spectrometry and molecular modeling techniques can characterize the selective metal chelating performance of designed metal-binding peptides and the copper-binding peptide methanobactin. Developing new classes of metal chelating peptides will help lead to therapeutics for diseases associated with metal ion misbalance.
