Webb27 sep. 2006 · Because PhoA has two intrachain disulphide bonds required for its native structure, and therefore for its enzymatic activity, only gene fusions encoding proteins, which displayed PhoA in the periplasm, would produce an active enzyme. The corresponding colonies can be readily detected on XP indicator plates (Fig. S1C). Webb7 apr. 2024 · Leaf Score. Highlights: De Buyer’s Mineral B Pan heats quickly, is easy to maneuver, and provides a virtually nonstick surface. However, this pan loses points for only being oven safe for a few minutes at a time, and it’s also very difficult to maintain seasoning. DeBuyer’s pans are PFAS, PFOA, and PTFE free.
