The stereospecific cytochrome P450-catalyzed hydroxylation of the C(5)-H((5-exo)) bond in camphor has been studied theoretically by a combined quantum mechanical/molecular mechanical (QM/MM) approach. Density functional theory is employed to treat the electronic structure of the active site (40-100 atoms), while
