title: Hydroxylation of oleanolic acid to queretaroic acid by cytochrome P450 from Nonomuraea recticatena.
abstract: A gene for cytochrome P450 (moxA) from Nonomuraea recticatena, coexpressed with camAB for pseudomonad redox partners in Escherichia coli, hydroxylated oleanolic acid to produce queretaroic acid. When we used the P450-induced whole-cell as a catalyst, only a small amount of queretaroic acid was produced, probably due to poor permeability of oleanolic acid into the E. coli cell. In an alternative approach with the cell-free reaction system, the conversion ratio increased up to 17%.
