Alteration of the interconversion of pyruvate and malate in the plastid or cytosol of ripening tomato fruit invokes diverse consequences on sugar but similar effects on cellular organic Acid, metabolism, and transitory starch accumulation

open access: yes, 2013
The aim of this work was to investigate the effect of decreased cytosolic phosphoenolpyruvate carboxykinase (PEPCK) and plastidic NADP-dependent malic enzyme (NADP-ME) on tomato (Solanum lycopersicum) ripening.

Stereochemische Entschlüsselung der Strobilurin‐PKS enthüllt die komplexe biosynthetische Logik des iterativen Aufbaus eines EZE‐Triens

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Die iterative Strobilurin‐PKS baut ein bemerkenswertes EZE‐Trien auf, indem es seine S‐tereoselektvität während der Synthese variiert. Die stereoselektive 2R‐Methylierung des Triketid‐Intermediats durch die C‐terminale C‐Methyltransferase‐Domäne induziert die KR‐ und DH‐Domänen ihre native Stereoselektivität umzukehren und ein Z‐konfiguriertes ...

Stereochemical Dissection of the Strobilurin PKS Reveals the Complex Biosynthetic Logic of Iterative EZE Triene Construction

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 4, 22 January 2026.
The strobilurin iterative PKS assembles a remarkable EZE triene by varying its stereoselectivity during synthesis. Stereoselective 2R‐methylation of the triketide intermediate by the C‐terminal C‐methyltransferase domain induces the KR and DH domains to invert their native stereoselectivities and produce a Z‐configured intermediate.

Asymmetric Catalytic Hydrogenation toward a Value‐Added Chiral Building Block: Optically Active γ‐Butyrolactone Scaffold from Renewable and Synthetic Derived Feedstocks

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 3, January 22, 2026.
This brief compendium summarizes the most successful asymmetric hydrogenation strategies for the preparation of chiral monocyclic γ‐lactone derivatives from keto acids and keto esters, with emphasis on their relevance for large‐scale production and high enatioselectivities. This article provides a brief compendium on the production of chiral monocyclic
