CYP2R1 is known to be a physiologically important vitamin D 25-hydroxylase. We have successfully expressed human CYP2R1 in Saccharomyces cerevisiae to reveal its enzymatic properties. In this study, we examined production of 25-hydroxylated vitamin D using whole recombinant yeast cells that expressed CYP2R1. When vitamin D3or vitamin D2was added to the cell suspension of CYP2R1-expressing yeast cells in a buffer containing glucose and β-cyclodextrin, the vitamins were converted into their 25-hydroxylated products. Next, we irradiated the cell suspension with UVB and incubated at 37°C. Surprisingly, the 25-hydroxy vitamin D2was produced without additional vitamin D2. Endogenous ergosterol was likely converted into vitamin D2by UV irradiation and thermal isomerization, and then the resulting vitamin D2was converted to 25-hydroxyvitamin D2by CYP2R1. This novel method for producing 25-hydroxyvitamin D2without a substrate could be useful for practical purposes.
