Summary of 18O incorporation from 18O2 into formic acid with five P450 51A enzymes. Results from Figures 2 and 3. All values were normalized for the content of 18O (from 18O2) incorporated into 17α-OH progesterone by P450 17A1. The individual points indicate the results of individual incubations (3), with the means ± SD. Separate trials were run on different days, each with a set of three more enzyme reactions. The stippled lines are set at 50 and 80% for reference.
