Identifizierung eines Aktivitätsselektors, der die Nitrosoaktivität in bakteriellen Typ‐III Kupferenzymen kontrolliert

Angewandte Chemie, Volume 137, Issue 26, June 24, 2025.
Ein kleiner, aber entscheidender Unterschied: Typ‐III‐Kupferenzyme, wie Tyrosinasen (TYRs) und o‐Aminophenoloxidasen (AOs), katalysieren die Oxidation von o‐Aminophenolen (AP) zu Chinoniminen. Im Gegensatz zu TYRs können AOs AP weiter zu Nitrosophenolen oxidieren.

Metabolic response of vitamin C and phenolic compounds in fresh‐cut pineapple induced by pulsed electric fields

Future Postharvest and Food, Volume 1, Issue 4, Page 454-465, December 2024.
The proposed scheme explains the mechanism of action of the pulsed electric field (PEF – 5 pulses) on the metabolism of vitamin C and phenolic compounds during refrigerated storage (10°C) of minimally processed pineapple. Abstract The loss of nutritional quality is the main factor associated with the perishability of minimally processed foods.
