Discovery and Biosynthesis of Celluxanthenes, Antibacterial Arylpolyene Alkaloids From Diverse Cellulose‐Degrading Anaerobic Bacteria [PDF]
Angewandte Chemie, Volume 137, Issue 24, June 10, 2025.The structure and biosynthetic origin of the enigmatic “yellow affinity substance” (YAS) from the anaerobe thermophile Clostridium thermocellum (now: Acetivibrio thermocellus) were elucidated. YAS is a complex of unusual antibacterial arylpolyene alkaloids (celluxanthenes) that are produced by various cellulolytic anaerobes.

Designer Glycolysomes: Colocalisation of Glycolytic Enzymes on a Cellulosome‐Based Synthetic Protein Scaffold [PDF]
Microbial Biotechnology, Volume 18, Issue 4, April 2025.The first three Escherichia coli glycolytic enzymes were converted to the docking enzyme mode and subsequently scaffolded. Increasing copies of the rate‐limiting enzyme boosted the overall performance. At lower enzyme densities, the proximity effects provided by scaffold‐colocalisation result in a higher product yield compared to free docking enzymes ...
