Gene map of recombinant plasmids with inserted P. phosphoreum lux genes. Recombinant pRFN4 plasmids used in this study: pRFN4, pRFN4-Pp N-lumP, pRFN4-Pp luxCP, pRFN4-Pp luxCP-N-lumP, and pRFN4-Pp luxLP-N-lumP plasmids. The nomenclature of riboflavin biosynthetic genes of B. subtilis differs from other species. Therefore, ribE in pRF2 and pRFN4 is the gene coding for riboflavin synthase in B. subtilis [5]. In pRFN4, the ribE gene coding for Phe 2 in riboflavin synthase was replaced with Ala for overproduction of lumazine (F2A in ribB) [13].
