The Hemoprotein Hhy1 Promotes Heme‐Dependent Catalase Activity of Ctt1
Molecular Microbiology, EarlyView.A Schizosaccharomyces pombe strain deficient in heme (hem1Δ) and siderophore (Fc) biosynthesis, as well as high‐affinity iron (Fe) uptake (blue), was used to uncover the hemoprotein Hhy1 that promotes the heme‐dependent activity of the catalase Ctt1. In contrast, hhy1Δ cells exhibit reduced Ctt1 activity and increased sensitivity to oxidative stress ...

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.Die Implementierung von Kronenethern in den Liganden von Kobaltporphyrinen wirkt sich in mehrfacher Hinsicht positiv auf die elektrochemische CO2‐Reduktion aus: 1. Das Reduktionspotenzial wird in Gegenwart von K+ gesenkt; 2. die CO‐Erzeugung in Zero‐Gap‐Elektrolyseuren wird gesteigert und 3.

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
