Molecular modelling of the mouse cytochrome P450 CYP2F2 based on the CYP102 crystal structure template and selective CYP2F2 substrate interactions.

The results of homology modelling of the mouse cytochrome P450, CYP2F2, are reported, based on the CYP102 crystallographic template. It is found that selective CYP2F2 substrates are able to fit the putative active site of the enzyme via aromatic pi-pi stacking and, in some cases, hydrogen-bonded interactions. Two alkylnaphthalenes were investigated via the model to evaluate whether they are likely to act as CYP2F2 substrates and, of these, 2-isopropyl-naphthalene was found to fit the putative active site, whereas 2-(2-hexadecyl)naphthalene was unable to do this, due to its bulky side-chain. Consequently, it is possible to utilize homology modelling to evaluate the likelihood of enzyme-substrate selectivity for CYP2F2 and predict routes of metabolism mediated by this enzyme. This procedure can therefore be used to investigate the potential for activation of xenobiotics via this enzyme, especially those related to known CYP2F substrates, such as naphthalene.[1]
