Nucleotide sequence, transcriptional analysis, and glucose regulation of the phenoxazinone synthase gene (phsA) from Streptomyces antibioticus. [PDF]
The nucleotide sequence of a 2.3-kb SphI fragment containing the structural gene (phsA) for phenoxazinone synthase (PHS) of Streptomyces antibioticus was determined. The sequence was found to contain an open reading frame (ORF) with a G+C content of 71.5% oriented in the direction of transcription that was confirmed by primer extension. The ORF encodes

Regulation of secondary metabolite biosynthesis: catabolite repression of phenoxazinone synthase and actinomycin formation by glucose. [PDF]
Synthesis of the secondary metabolite, actinomycin, and the enzyme, phenoxazinone synthase, involved in the biosynthesis of the antibiotic, were shown to be under severe catabolite repression by glucose. Of a variety of hexoses and carbon compounds examined, glucose, and to a lesser extent, mannose, proved to be the most repressive for enzyme synthesis.

The motivation to find functional models of different metalloenzymes comes from their potential to develop better catalysts inspired by nature. Generally, metalloenzymes can activate aerial dioxygen due to the metal ions in it.

Activation of phenoxazinone synthase expression in Streptomyces lividans: characterization of the activator fragment from Streptomyces antibioticus [PDF]
We have isolated an active 719 bp fragment from the 4.3 kb region of the genome of Streptomyces antibioticus that activates a silent phenoxazinone synthase (PHS) gene in Streptomyces lividans. Sequencing of the 719 bp fragment revealed several potential open reading frames (ORFs); however, the distribution of G + C in these putative ORFs was ...
