Reverse prenylation in plants by non‐canonical aromatic prenyltransferases
The Plant Journal, Volume 122, Issue 6, June 2025.Significance Statement Aromatic prenyltransferases (aPTs) are key catalysts in plant specialized metabolism, enhancing bioactivity by attaching hydrophobic prenyl groups to aromatic compounds. While no plant aPT catalyzing reverse prenylation of aromatic carbons has been identified so far, this study reports plant UbiA‐type aPTs from Hypericum species,

Chemoselective or Regioselective?
ChemistryEurope, Volume 3, Issue 3, May 2025.The current definitions of chemoselectivity and regioselectivity lack sufficient clarity and allow for the ambiguous labeling of reported reaction selectivities in some instances. This article proposes a rationale and simplified definitions of these terms that will facilitate an unambiguous description of the observed reaction selectivity.
