Characterisation of the katA gene encoding a catalase and evidence
... A KatA-de¢cient strain of S. xylosus, designated TX350, was constructed by exchanging the 5P-end of katA for an erythromycin resistance gene, ermB (Fig. 1B). By this replacement, the ¢rst 60 codons of katA including the start codon and ribosome-binding site were removed resulting in a complete block ...
