ER peptides formed condensates and remodeled CR aggregates from ordered amyloid-like structures into more disordered conformations. Bile acids promoted CR disassembly and proteolysis, whereas ER condensates sequestered bile acids and restricted their access to CR. Confocal imaging supported the spatial isolation of bile acids by ER condensates. Bile acids also enhanced epithelial transport and strengthened interactions between CR aggregates and mimetic lipid bilayers, whereas these effects were attenuated by ER-mediated bile acid sequestration. Our findings support a role for bile acid availability in modulating CR digestibility and transepithelial transport, linking peptide condensation, bile acid homeostasis, and protein functionality.","PeriodicalId":41,"journal":{"name":"Journal of Agricultural and Food Chemistry","volume":"12 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2026-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149359465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heat stress and exogenous H2O2 induced PoCAT2 expression and wall-associated catalase activity. Unlike intracellular PoCAT1, PoCAT2 overexpression increased catalase activity in both intracellular and cell wall compartments, enhancing in situ H2O2 scavenging and promoting mycelial growth under both optimal and elevated temperatures.
