Peroxiredoxins (PRDXs) eliminate reactive oxygen species such as hydrogen peroxide through a catalytic cycle of Cys oxidation and reduction. Additionally, upon Cys oxidation PRDXs undergo extensive conformational rearrangements that may underlie their presently structurally poorly defined functions as molecular chaperones. Rearrangements include high molecular-weight oligomerization, the dynamics of which are, however, poorly understood, as is the impact of disulfide bond formation on these properties. Here we show that formation of disulfide bonds along the catalytic cycle induces extensive μs time scale dynamics, as monitored by magic-angle spinning NMR of the 216 kDa-large Tsa1 decameric assembly and solution-NMR of a designed dimeric mutant. We ascribe the conformational dynamics to structural frustration, resulting from conflicts between the disulfide-constrained reduction of mobility and the desire to fulfill other favorable contacts.","lang":"eng"}],"department":[{"_id":"PaSc"}],"issue":"19","date_published":"2023-05-04T00:00:00Z","publication_status":"published","pmid":1,"date_updated":"2023-08-01T14:48:09Z","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"month":"05","article_processing_charge":"No","day":"04","type":"journal_article","file":[{"relation":"main_file","checksum":"0758a930ef21c62fc91b14e657479f83","file_name":"2023_JACS_Troussicot.pdf","access_level":"open_access","creator":"dernst","content_type":"application/pdf","date_updated":"2023-05-30T07:05:28Z","date_created":"2023-05-30T07:05:28Z","file_size":6719299,"file_id":"13098","success":1}]}
