This paper focuses on study of second and third ring cyclization in anthracycline biosynthesis by a heterologous gene expression. Firstly, anthracycline non-producing Streptomyces peucetius mutant, D2 was heterologously complemented to produce daunom

In this study a set of Streptomyces galilaeus ATCC 31615 mutants was characterized, which are incapable of synthesizing some or all of the deoxyhexose sugars of aclacinomycin A. Complementation experiments with the the mutant strains H026, H038, H039

We have cloned and sequenced polyketide synthase (PKS) genes from the aclacinomycin producer Streptomyces galilaeus ATCC 31,615. The sequenced 13.5-kb region contained 13 complete genes. Their organization as well as their protein sequences showed hi

The anthracycline skeleton is biosynthesized by aromatic (type II) polyketide synthases. Furthermore, three post-polyketide steps are needed to form the basic aglycone of anthracyclines. Auramycinone was produced in Streptomyces lividans by introduci

Degenerated oligonucleotide primers were designed to amplify fragments of ketosynthase genes from polyketide antibiotics producing Streptomyces spp. and bacterial strains enriched from soil samples. Cell lysates were used as templates in amplificatio

Compounds produced by the polyketide ketoreductase deficient Streptomyces mutants HO61 and P67 are described. The structures of the compounds indicate that ketoreductase activity is required for correct condensation of the polyketide chain in the bio

Background: Mithramycin, nogalamycin and aclacinomycins are aromatic polyketide antibiotics that exhibit antitumour activity. The precursors of these antibiotics are formed via a polyketide biosynthetic pathway in which acetate (for mithramycinone an

Streptomyces steffisburgensis (NRRL 3193, ATCC 27466) is described as a steffimycin producer. Steffimycin belongs to the anthracycline group of aromatic polyketide antibiotics. The structural analysis of the products accumulated by the wild type ATCC
