1.14.14.24 A241G/L243V/F244L/P245R/R246F mutation in substrate recognition site 3, to the equivalent residues in CYP2D6, an enzyme not active in 25-hydroxylation. The 25-hydroxylase activity of the mutant is completely lost whereas the activity toward tolterodine remains virtually unaffected Sus scrofa
