AKR1D1_his

A human 5-beta reductase used in bile acid synthesis. Used in the 2022 McGill project to catalyze the second step of the cholesterol -> coprostanol pathway, which is 4-cholesten-3-one to coprostanone. Coprostanol cannot be absorbed by the gut, which is a unique property.

Results

Figure 3. GC-MS chromatogram of three AKR1D1 pop assays in E. coli mixed with cholestenone substrate. The GC-MS chromatogram shows the 0.01% coprostanone standard along with the product of a three AKR1D1 reactions containing, 100µM cholestenone, 500µM NADPH, 100mM potassium phosphate buffer (pH 6.0), 0.2% Triton X-100, and 5% ethanol, incubated for 16 hours at 37°C. AKR1D1 was added to the reaction using the pop assay protocol. The AKR1D1 reaction chromatogram shows a peak directly underneath the coprostanone standard, indicating product formation using the pop assay protocol.
