Klassische Knorr‐Chemie trifft auf moderne Biokatalyse. Die Threonindehydrogenase erzeugt aus l‐Threonin Aminoaceton, welches direkt in einer chemoenzymatischen Knorr‐Pyrrolsynthese abgefangen wird. Ein bifunktionales β‐Dicarbonylsubstrat dient sowohl als Pyrrolbaustein als auch als Hydridakzeptor für integrierte NAD+‐Recyclierung und ermöglicht die ...

Effect of a New Natural Seasoning on the Formation of Pyrazines in Barbecued Beef Patties
The formation of pyrazines in food cooking is required to obtain satisfactory “roasted” flavor. The aim of this work was to evaluate the effect of a new red wine pomace seasoning (RWPS) on the formation of pyrazines in barbecued beef patties.

Dual‐Function Cosubstrates Enable Threonine Dehydrogenase‐Driven Chemoenzymatic Pyrrole Synthesis
Classical Knorr chemistry meets contemporary biocatalysis. Threonine dehydrogenase generates aminoacetone from l‐threonine, which is directly intercepted in a chemoenzymatic Knorr pyrrole synthesis. A dual‐function β‐dicarbonyl substrate serves as both pyrrole precursor and hydride acceptor for integrated NAD+ recycling, affording substituted pyrroles ...
