Sentence examples for cpd I from inspiring English sources

Recent modeling studies suggest that the oxidation of H2O2 by catalase Cpd I may take place by two hydrogen atom transfer steps.

However, whereas catalase Cpd I oxidizes a second H2O2 molecule to oxygen, peroxidases use this intermediate to oxidize other substrates rather than H2O2.

If conversion of the hydroperoxo ferriheme species to Cpd I does not occur until higher temperatures, then it is possible for Cpd I to accumulate, as seen for Cpd I of β-chains.

The decreased yield of Cpd I at low pH thus may be attributed to more effective reduction of Cpd I, possibly along with its lower intrinsic stability.

At high pH, Cpd I accumulates and was characterized by EPR/ENDOR.

In all other cases, Cpd I forms but does not accumulate.

[3] It has been suggested that the anionic Cys donor in CYP450 plays an important role in modulating the electronic features and reactivity of the high-valent iron oxo species FeIV O)(porph+.)(Cys) (Compound-I: Cpd-I), which is the critical intermediate responsible for substrate oxidation.

[4] These previous studies have shown that both anionic and neutral donors have had a significant influence on the reactivity of the Cpd-I analogues, with reaction rates typically being influenced by 1 3 orders of magnitude.

The analogous influence of axial ligands on high-valent Mn oxo complexes has been less well studied, in part because Cpd-I analogues MnIV O)(porph+.), or the equivalent MnV(O)(porph), are typically highly unstable and difficult to observe.

This change can be compared to recent work by Fujii, which showed that modifying the nature of the axial ligand in an iron oxo porphyrin Cpd-I analogue resulted in a 30-fold difference in OAT rate.

[3] The influence of axial ligands on the reactivity of synthetic Cpd-I analogues has been examined for several reaction classes, including alkyl and arene hydroxylation, and alkene epoxidation.
