Rewiring Steroidal Metabolic Pathways for Diosgenin Production in Solanum nigrum

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3032-3047, May 2026.
ABSTRACT Diosgenin is a key starting material for the synthesis of steroidal drugs, such as corticosteroids and sex hormones. While the primary commercial source of diosgenin is the tubers of Dioscorea spp., identifying alternative plant hosts capable of diosgenin biosynthesis could enhance its production.

Biocatalytic Potential of a Mycobacterial Aminoacylase for Synthesis of N‐Acyl‐L‐Amino Acids in Aqueous Media

ChemBioChem, Volume 27, Issue 7, 14 April 2026.
The aminoacylase MsAA is a suitable enzyme for the biotechnological production of N‐acyl‐L‐amino acids. This study focuses on the optimization of the synthesis of N‐lauroyl‐L‐methionine. A detailed analysis of the catalytic reaction mechanism of MsAA is performed in an in silico protein modeling study.
