1 Polymers of cytochrome c carboxymethylated on the methionine residue normally ligated to iron show simple CO recombination kinetics after photolytic removal (k(on)=1.5x10(6)m(-1).s(-1) at pH6). Iron cytochrome c, somatic Equus caballus
2 We therefore suggest that, for native cytochrome c, polymerization has an effect on the lability of the haem crevice, rendering the iron available for binding ligands, without, however, forming the structure of a truly open crevice. Iron cytochrome c, somatic Equus caballus
