Catalytic Amyloids: Turning Fibrils Into Biocatalysts

Chemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
Amyloids, traditionally associated with diseases, have emerged as versatile catalytic scaffolds. From natural amyloid sequences to bioinspired and de novo designs, we highlight strategies to construct catalytic active sites and anchor enzymes onto fibrils, creating versatile nanomaterials with tunable activities. ABSTRACT Amyloids have been regarded as

5,15-Diaryl-beta-substituted-porphyrinato-manganese(III) chlorides as probes for structure-activity relationships in porphyrin-based epoxidation catalysts [PDF]

, 2001
Manganese complexes of 5,15-diaryl-beta-substituted-porphyrins were prepared and their behaviour as oxidation catalysts was studied. The role of the pyrrolic and meso-substituents on the activity and selectivity of these catalysts was studied to reveal ...
