| Abstract: | The transformation of Bacillus subtilis Lys- strains with plasmid pLRS33 containing pBR322 and the Bac. subtilis chromosomal fragment carrying the genes for lysin biosynthesis and the riboflavin operon regulatory operator region (ribO) leads to the appearance of Rib- mutants. It was shown that these mutants contained long deletions covering a great portion of the riboflavin operon. |
