Die violette Wolke (HasA; ein Häm‐Akquisitionsprotein) liefert Cobalt‐Oxaporphyrinium (oranges Porphyrin und roter Sauerstoff) zu Pseudomonas aeruginosa (grün). Rekonstruiertes HasA hat die Fähigkeit, Pseudomonas aeruginosa abzutöten. Die im Bild gezeigte Weide symbolisiert die Wachstumshemmung von Pseudomonas aeruginosa durch rekonstruiertes HasA. Details dieser Studie finden sich in der Zuschrift...
Using artificial hemes for the reconstruction of natural heme proteins represents a fascinating approach to enhance the bioactivity of the latter. We report the synthesis of various metal 5‐oxaporphyrinium cations as cofactors, and a cobalt 5‐oxaporphyrinium cation was successfully incorporated into the heme‐acquisition protein (HasA) secreted by Pseudomonas aeruginosa. We hypothesize that the oxaporphyrinium...
