Modified xylE and xylTE reporter genes for use in Streptomyces: analysis of the effect of xylT

Abstract The reporter gene xylE (encoding catechol 2,3-dioxygenase) has been modified for a more rational use in Streptomyces. Two reporter fragments, one containing xylE, and the other containing also the upstream gene xylT (which encodes a soluble ferredoxin), have been constructed to allow precis...

description Abstract The reporter gene xylE (encoding catechol 2,3-dioxygenase) has been modified for a more rational use in Streptomyces. Two reporter fragments, one containing xylE, and the other containing also the upstream gene xylT (which encodes a soluble ferredoxin), have been constructed to allow precise fusion of regulatory regions to the reporter genes. Identical fusions of these xylE and xylTE reporter fragments to the Streptomyces dagA and tipA promoters, in low and high copy number plasmids, show that the levels of xylE mRNA and catechol 2,3-dioxygenase activities are significantly higher when xylT is present.
