Fig. 2From: Development of a strictly regulated xylose-induced expression system in Streptomycesa Gene organization in the intergenic region containing the xyl operon of S. avermitilis MA-4680 from the complete genome sequence. b The nucleotide sequence of the intergenic promoter region of the divergently transcribled xylA and xylB genes of S. avermitilis. The putative ribosome binding sites from S. rubiginosus are shown as underlined sequences [24]Back to article page
