Results of sensitizer-wire/protein experiments with cytochrome P450cam and iNOS. Superscripts denote references. Subscripts: (a) distances inferred from [Re-Im-F₉bp]⁺; (b) the heme was reduced using a flash/quench method; (c) the heme was reduced using a flash/quench method but a rate was not determined; (d) the heme was reduced directly from Ru(II)* or Re(I)*
