FIG. 5.
Plasmids pAY703 and pAY1108. The structures of the chromosomal mgl locus are shown for wild-type M. xanthus and for recombinant merodiploid strains with integrated plasmid vectors pAY703 and pAY1108. Recombinant strains with plasmid pAY1108 express the E. coli glk (glucokinase) gene from the constitutive mglBA promoter. The level of glucokinase expression in M. xanthus is the same as its basal level of expression in E. coli (28).
