Zn	the recombinant enzyme, expressed in Pseudomonas putida, contains c-heme but no d1-heme. Reconstitution of this protein with Zn-protoporphyrin IX in the place of the d1-heme. Photoexcitation of Zn-NIR is followed by electron transfer from the triplet excited state of the Zn-porphyrin to the oxidized c-haem. Reduction of the d1-heme is associated with a substantial reorganization of the coordination of the metal	Pseudomonas aeruginosa
