title: Bioconversion of the anthracycline analogue desacetyladriamycin by recombinant DoxA, a P450-monooxygenase from Streptomyces sp. strain C5.
abstract: [reaction: see text] A recombinant P450-monooxygenase, DoxA, obtained from Streptomyces sp. strain C5, the producer of the anticancer compound daunorubicin, was expressed in S. lividans TK24 and therein used to catalyze the conversion of the anthracycline analogue desacetyladriamycin into the new anthracycline, 10-hydroxydesacetyladriamycin. This work establishes a new function for DoxA and demonstrates the use of a recombinant enzyme to prepare a new anthracycline analogue.
