Abstrakt: Characterization of the dnmZ, dnmU, and dnmV genes from the daunorubicin-producer Streptomyces peucetius by DNA sequence analysis indicated that these genes encode a protein of unknown function plus a putative thymidine diphospho-4-keto-6-deoxyglucose-3(5)-epimerase and thymidine diphospho-4-ketodeoxyhexulose reductase, respectively. Inactivation of each of the three genes by gene disruption and replacement in the wild-type strain demonstrated that all of them are required for daunosamine biosynthesis.
