Novel Biocatalysts from Specialized Metabolism

open access: yesAngewandte Chemie, Volume 136, Issue 4, January 22, 2024.
Enzymes are increasingly valuable as biocatalysts in synthetic chemistry. Many novel biocatalysts have emerged from the study of secondary metabolism, where rare and unusual reactions take place. In this review, we explore biocatalysts that address various synthetic challenges, including cyclization, C−H functionalization, and cross‐coupling, among ...

Acetylation‐Deacetylation‐Driven Natural Product Biosynthesis

open access: yesChemistryEurope, Volume 3, Issue 4, July 14, 2025.
This review summarizes the role of acetylation‐deacetylation in natural product biosynthesis, including acetylation followed by deacetylation after several biosynthetic steps, acetylation‐mediated rearrangement, acetylation‐triggered elimination, and the acetylation cycle as a regulatory mechanism. These processes are vital for the formation of complex

Cell‐type‐aware regulatory landscapes governing monoterpene indole alkaloid biosynthesis in the medicinal plant Catharanthus roseus

open access: yesNew Phytologist, Volume 245, Issue 1, Page 347-362, January 2025.
Summary In plants, the biosynthetic pathways of some specialized metabolites are partitioned into specialized or rare cell types, as exemplified by the monoterpenoid indole alkaloid (MIA) pathway of Catharanthus roseus (Madagascar Periwinkle), the source of the anticancer compounds vinblastine and vincristine. In the leaf, the C.
