Increasing Complexity of a Diterpene Synthase Reaction with a Single Residue Switch [PDF]

open access: yes, 2008
Terpene synthases often catalyze complex reactions involving intricate series of carbocation intermediates. The resulting, generally cyclical, structures provide initial hydrocarbon frameworks that underlie the astonishing structural diversity of the ...

Advances in large DNA fragment assembly for microbial cell factory engineering

open access: yesQuantitative Biology, Volume 14, Issue 3, September 2026.
Abstract The efficient, rapid, and reliable assembly of DNA fragments is essential for advancing metabolic engineering and synthetic biology. With the rapid advancement of DNA synthesis and assembly technologies, the scale of DNA assembly has expanded from single genes to metabolic pathways and even genomes.

Pushing the limits of concertedness. A waltz of wandering carbocations. [PDF]

open access: yes, 2019
Among the array of complex terpene-forming carbocation cyclization/rearrangement reactions, the so-called "triple shift" reactions are among the most unexpected.

Genome association of carbohydrate metabolites provides new insights toward functional breeding in coffee

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Coffee is one of the world's most widely consumed beverages, derived mainly from Coffea arabica, known for its superior flavor, and Coffea canephora (Robusta/Conilon), valued for its resilience and higher caffeine content. Functional breeding aims to develop cultivars that combine productivity and stress tolerance with improved health‐related ...

Synthesis and Study of the Structure–Activity Relationship of Antiproliferative N-Substituted Isosteviol-Based 1,3-Aminoalcohols

open access: yesPharmaceuticals
Starting from isosteviol, a series of diterpenoid 1,3-aminoalcohol derivatives were prepared via stereoselective transformations. The acid-catalysed hydrolysis and rearrangement of natural stevioside produced isosteviol, which was transformed into the ...

Uprolides N, O and P from the Panamanian Octocoral Eunicea succinea. [PDF]

open access: yes, 2016
Three new diterpenes, uprolide N (1), uprolide O (2), uprolide P (3) and a known one, dolabellane (4), were isolated from the CH₂Cl₂-MeOH extract of the gorgonian octocoral Eunicea succinea, collected from Bocas del Toro, on the Caribbean coast of Panama.

Bioconversion of carotenoids into high‐value crocins using a marine sponge carotenoid cleavage dioxygenase

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3230-3246, June 2026.
Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites

Biotransformations of Imbricatolic Acid by Aspergillus niger and Rhizopus nigricans Cultures

open access: yesMolecules, 2007
Microbial transformation of imbricatolic acid (1) by Aspergillus niger afforded 1α-hydroxyimbricatolic acid (2), while transformation with Rhizopus nigricans yielded 15-hydroxy-8,17-epoxylabdan-19-oic acid (3).
