Engineering membrane‐bound alkane monooxygenase from Marinobacter sp. for increased activity in the selective ω‐hy‐droxylation of linear and branched aliphatic esters

Protein Science, Volume 35, Issue 4, April 2026.
Abstract The regio‐ and stereoselective hydroxylation of unactivated C(sp3)‐H bonds is an important reaction in organic synthesis. While bacterial alkane monooxygenase AlkB catalyzes the terminal hydroxylation of aliphatic esters with excellent regioselectivity, the molecular principles of substrate recognition and selectivity of this integral membrane

N‐Heterocyclic Tetrylenes with a 1,1′‐Ferrocenylene Backbone and Bis(2,4,6‐triisopropylphenyl)boryl N‐Substituents

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 4, 17 March 2026.
Ferrocene‐based N‐heterocyclic tetrylenes [Fe{(η5‐C5H4)NBTrip2}2E](E = GePb; Trip = C6H2‐2,4,6‐iPr3)exhibit long EN and short BN bonds, in agreement with increased electrophilicity due to the ‐M effect of the N‐substituents, whose stericdemand prevents coordination of 4‐(dimethylamino)pyridine (DMAP) to theplumbylene PbII atom, but allows the ...

The Diarylprolinol Silyl Ethers: After 20 Years Still Opening New Doors in Asymmetric Catalysis

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
Catalysis Rules! The year 2025 marks the 20th anniversary of diarylprolinol silyl ethers in asymmetric organocatalysis. During the first decade after their discovery, these catalysts have been established as one of the most versatile tools in aminocatalysis. Although now considered mature, recent years have witnessed renewed innovation.

Designed Water Capture in Terpene Synthase Catalysis

ChemBioChem, Volume 27, Issue 5, 13 March 2026.
Engineering of water capture in terpene synthases remains very challenging. We identified two regions in the selinadiene synthase active site pocket that can influence deprotonation or water capture in the final catalytic step and demonstrate a designed‐in switch in product outcome.
