Activating Compound | Comment | Organism | Structure |
---|---|---|---|
cumene hydroperoxide | considerable amount of the putative Cpd II species accumulates, even at pH 7.4. By contrast, reactions with meta-chloroperbenzoic acid at pH 7.4 yield very little of the ca. 420 nm species, unless methanol is included | Pseudomonas putida | |
methanol | reaction with meta-chloroperbenzoic acid in the presence of methanol (3% or ca. 1 M after mixing) at pH 7.4 and 25°C results in the accumulation of a considerable fraction of the P450cam as the putative Cpd II species | Pseudomonas putida |

additional information | in contrast to the wild-type, the more hydrophobic sites of the Tyr-to-Phe variants, compared to that of wild-type, favor homolysis more strongly and lead to considerable fractions of the Cpd II like species in reactions with peracids, especially at higher pH | Pseudomonas putida |
Y75F | reaction with meta-chloroperbenzoic acid at 25°C, pH 8.0, is similar to that with the Y96F variant, although slightly more Cpd I (and possibly some Cpd ES) is present | Pseudomonas putida |
Y96F | reaction with peracetic acid at pH 8.0, 25°C, is similar to that with meta-chloroperbenzoic acid, except that even with 2.4 mM peracetic acid, all steps are slower than those with 0.150 mM meta-chloroperbenzoic acid | Pseudomonas putida |
Y96F/Y75F | mutants produce changes in hydrogen bonding patterns and increase hydrophobicity that affect the ratio of heterolytic to homolytic pathways in reactions with cumene hydroperoxide, resulting in a shift of this ratio from 84/16 for wild-type to 72/28 for the Y96F/Y75F double mutant | Pseudomonas putida |

(+)-camphor + O2 + reduced putidaredoxin | the Cpd II-like species is ineffective at hydroxylating camphor, but can be readily reduced by ascorbate to ferric P450cam, which can then bind camphor to form the high-spin heme | Pseudomonas putida | exo-5-hydroxycamphor + oxidized putidaredoxin + H2O | - |

cytochrome | state of cytochrome that is two equivalents of oxidation greater than the ferric form (Cpd I species), state of cytochrome that is one equivalent of oxidation greater than the ferric form (Cpd II species), two-electron-oxidized state of P450 or peroxidases containing both an oxoferryl center [FeIV=O] and either a tryptophanyl or tyrosyl radical, analogous to Cpd ES in cytochrome c peroxidase (Cpd ES species) | Pseudomonas putida | |
