1.11.1.5 | more |
catalytic center activity increases with ionic strength in the case of cytochrome c551, with horse heart cytochrome c, the catalytic center activity decreases exponentially |

1.11.1.5 | Fe |
static titration of ferric cytochrome c peroxidase with reduced azurin shows that only one of the two hemes in the enzyme seems to be readily reduced |

1.11.1.5 | Ca2+ |
a single, tightly bound, Ca2+ ion at the domain interface of both the fully oxidized and mixed-valence forms of the enzyme is absolutely required for catalytic activity, reduction of the electron-transferring (high-potential) heme in the presence of Ca2+ ions triggers substantial structural rearrangements around the active-site (low-potential) heme to allow substrate binding and catalysis |

1.11.1.5 | Ca2+ |
with added Ca2+, the peroxidatic heme is five-coordinate high-spin and active |
