WebThe reduced Heme a3 and CuB can now bind 1 O2 4. As O2 binds, it will pull one e- from Fe 2+ and Cu+ to FORM a peroxide bridge 5. Two more e- are transferred from 2 reduced Cyt C, and will BREAK the peroxide bridge with help of 2H+ (from matrix) 6. An additional 2 more H+ (from matrix) forms 2H2O WebHeme-copper oxidases catalyze the four-electron reduction of O2 to H2O at a catalytic site that is composed of a heme group, a copper ion (CuB), and a tyrosine residue.
