The protein, belonging to the immunoglobulin superfamily, in common to other members of this family, experiences during its folding a long-lived intermediate associated to the trans-to-cis isomerization of Pro-32 that has been addressed as the precursor of the amyloid fibril formation. In this respect, previous studies on the W60G β2m mutant, showing that the lack of Trp-60 prevents fibril formation in mild aggregating condition, prompted us to reinvestigate the refolding kinetics of wild type and W60G β2m at atomic resolution by real-time NMR. The analysis, conducted at ambient temperature by the band selective flip angle short transient real-time two-dimensional NMR techniques and probing the β2m states every 15 s, revealed a more complex folding energy landscape than previously reported for wild type β2m, involving more than a single intermediate species, and shedding new light into the fibrillogenic pathway. Moreover, a significant difference in the kinetic scheme previously characterized by optical spectroscopic methods was discovered for the W60G β2m mutant.","lang":"eng"}],"publication":"Journal of Biological Chemistry","publication_status":"published","issue":"8","type":"journal_article","extern":"1","volume":285,"date_updated":"2021-01-12T08:19:31Z","language":[{"iso":"eng"}],"intvolume":"       285","publication_identifier":{"issn":["0021-9258","1083-351X"]}}
