Figure 1From: DNA phosphorothioation in Streptomyces lividans: mutational analysis of the dnd locusLocalization of the boundaries for dnd gene cluster. pSET152-derivatives with the ability to confer Dnd (+ or -) phenotypes are indicated in line with their insert fragments. Five arrows from left to right represent five the ORFs of the dnd gene cluster (dndA-E). Directions of the arrows indicate the transcriptional directions of the genes.Back to article page
