Structural changes observed in substrate access channels in the WT and mutants identified by Caver 3.0. (A) The initial model of WT CYP27A1 shows 2 channels, I and II. From this point on, the channels were also monitored in the MPCC of (B) WT, (C) M1, (D) M2, (E) M3, (F) M4, (G) M5, (H) M6, and (I) M7.
