1 (1) The hydrophilic sulfate group directs the steroid molecule so that it only interacts with the active site of cytochrome P-450 with its non-sulfurylated, hydrophobic end. Steroids cytochrome P450 family 4 subfamily F member 3 Homo sapiens
2 (2) The sulfate group interacts with the enzyme surface resulting in exposure of a slightly different part of the hydrophobic end of the substrate to the active site of cytochrome P-450 than when the same end of the free steroid is exposed to the active site of the enzyme.
