| Time-resolved UV/visible absorption spectroscopy on heme proteins. (a) Three-well model describing ligand binding in Mb. (b) Schematic depiction of a two-step rebinding process. Fast step: geminate rebinding. Slow step: bimolecular rebinding. N I,S : fraction of ligands that rebind internally/from the solvent. λ I,S: rate coefficients. Inset: Steady-state absorption spectra of a CO-ligated (black) and a deligated ferrous (red) heme (here: Mb). |
