Abstract excerpt
We have selected a Bacillus subtilis 168-borne xylR Ser to Leu mutation at position 41 of the encoded amino acid sequence showing a constitutive expression phenotype for the xyl operon. When cloned on a multi-copy plasmid in a B. megaterium strain harbouring a single-copy xylA-lacZ fusion it lead...
