Differential time-dependent inactivation of P450 3A4 and P450 3A5 by raloxifene: a key role for C239 in quenching reactive intermediates.
The role of C239 as the active-site residue responsible for forming the covalent linkage with raloxifene during P450 3A4 time-dependent inactivation (TDI) was recently identified. The correspondingExpand
