manganese lipoxygenase (Mn-LO) oxygenates 18:3n-3 and 18:2n-6 to bis-allylic 11S-hydroperoxy fatty acids, which are converted to 13R-hydroperoxy fatty acids.

We report the computational design of de novo proteins that bind Mn(salen)‐based complexes (L1) using Rosetta FastDesign and verified by AlphaFold2. After screening, the catalytic activity for the promising design (dnMSBP) toward enantioselective sulfoxidation of thioanisole was optimized based on its crystal structure. With 10 different substrates, we

Nitrogenases are the only enzymes able to fix gaseous nitrogen into bioavailable ammonia and hence are essential for sustaining life. Catalysis by nitrogenases requires both a large amount of ATP and electrons donated by strongly reducing ferredoxins or ...

Carbonic Anhydrases: Role in pH Control and Cancer
The pH of the tumor microenvironment drives the metastatic phenotype and chemotherapeutic resistance of tumors. Understanding the mechanisms underlying this pH-dependent phenomenon will lead to improved drug delivery and allow the identification of new ...

A Conserved Isoleucine Gates the Diffusion of CO and O2 to the Active Site of NiFe CO‐Dehydrogenase
A combination of protein film electrochemistry and site‐directed mutagenesis shows that isoleucine 563 (numbering of Thermococcus sp. AM4) gates the arrival of both CO and O2 to the active site of the nickel‐iron CO dehydrogenases. Mutations at this position increase the resistance to O2 at the cost of a slower reaction with CO.

The motivation to find functional models of different metalloenzymes comes from their potential to develop better catalysts inspired by nature. Generally, metalloenzymes can activate aerial dioxygen due to the metal ions in it.

An enantioselective photometallobiocatalytic cross‐coupling of pyridotriazoles and secondary alkyltrifluoroborate salts is developed. Cooperative catalysis using eosin B and an engineered protoglobin combines visible‐light‐mediated radical generation with enzymatic metal carbenoid activation, affording valuable N‐heterocyclic products in excellent ...
