The root causes of the outcomes of the single-site mutation in enzymes remain by and large not well understood. This is the case of the F429H mutant of the cytochrome P450 (CYP) 2B4 enzyme where the substitution, on the proximal surface of the active site, of a conserved phenylalanine 429 residue with histidine seems to hamper the formation of the active species, Compound I (porphyrin cation radical-Fe(IV) = O, Cpd I) from the ferric hydroperoxo (Fe(III)OOH-, Cpd 0) precursor. Here we report a… Expand

How is the reactivity of cytochrome P450cam affected by Thr252X mutation? A QM/MM study for X = serine, valine, alanine, glycine.
The present study provides a detailed mechanistic understanding of the role of the Thr252 residue and confirms the assumption that uncontrolled proton delivery by solvent water networks is responsible for the uncoupling reaction. Expand
How Does the Reductase Help To Regulate the Catalytic Cycle of Cytochrome P450 3A4 Using the Conserved Water Channel?
The CPR binding has a function: it triggers the aqueduct’s opening and thereby enables a proton shuttle pathway, which is needed for the dioxygen activation, which could be a general paradigm in P450s. Expand

Differences between the structures of 2C5 and 2B4 suggest that defined regions of xenobiotic metabolizing P450s may adopt a substantial range of energetically accessible conformations without perturbing the overall fold, likely to facilitate substrate access, metabolic versatility, and product egress.

New features in the catalytic cycle of cytochrome P450 during the formation of compound I from compound 0.
DFT is applied to the dark section of the catalytic cycle of the enzyme cytochrome P450, namely, the formation of the active species, Compound I, from the ferric-hydroperoxide species (Cpd 0) by a protonation-assisted mechanism and the essential role of Thr(252) as a hydrogen-bond acceptor is addressed.
