Activation of phenoxazinone synthase expression in Streptomyces lividans by cloned DNA sequences from Streptomyces antibioticus.

Journal of Biological Chemistry, 1984
Recombinant plasmids carrying Streptomyces antibioticus DNA (phenoxazinone synthase plasmids 1.8 and 4.3) have been used as templates in a streptomycete-coupled transcription-translation system. Analysis of the synthetic products from these experiments shows that PHS 1.8 and 4.3 appear to code for polypeptides which are not structurally related, as ...

Pitucamycin: Structural Merger of a Phenoxazinone with an Epoxyquinone Antibiotic

, 2016
Chemical profiling of a Streptomyces griseus strain isolated from an old building with moisture damage led to the discovery of two novel phenoxazinones, chandrananimycin D (1) and pitucamycin (2), along with the known grixazone B (3).
