S‐Adenosyl‐d‐Methionine as a Non‐Physiological Substrate for a Wide Range of SAM‐Dependent Enzymes

open access: yesChemBioChem, Volume 27, Issue 14, 29 July 2026.
From methylation and cyclisation to radical chemistry, diverse enzyme classes utilise the non‐canonical cofactor d‐SAM. These findings reveal an unexpected tolerance of SAM‐dependent catalysis towards inversion of the methionine Cα stereocentre. The ability of SAM‐dependent enzymes to accept S‐adenosyl‐d‐methionine [d‐SAM, (SS,RCα)‐SAM] instead of the ...

Light‐Activated Communication Between Synthetic and Living Cells via Photoresponsive Membranes

open access: yesChemBioChem, Volume 27, Issue 14, 29 July 2026.
Light‐triggered membrane rupture of SCs enables controlled release of adenosine triphosphate (ATP) and histamine, which activate purinergic and histaminergic signaling in HeLa cells, leading to intracellular Ca2+ mobilization. This biomimetic communication platform provides a simple strategy for engineering remotely controlled chemical signaling ...

Characterizing the Source and Formation of Gaseous Nitrated Phenolic Compounds in Urban Shanghai

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Nitrated phenolic compounds (NPs) are important components of brown carbon and contribute to the formation of HONO and OH radicals, yet their gas‐phase abundance and formation mechanisms in polluted urban environments remain poorly understood.
