Cloning of Beneckea genes in Escherichia coli

Abstract

Genes from Beneckea harveyi, a luminescent marine bacterium, were cloned in Escherichia coli. This was done by producing randomly sheared fragments of Beneckea DNA and inserting them into the EcoRI site of plasmid pMB9 by the adenine-thymine joining procedure. The hybrid plasmids were used to transform E. coli C600 SF8. Among the transformants selected for tetracycline resistance, one clone that appeared to complement a leucine tb mutation was identified. The transformants were screened for the presence of Beneckea 5S genes. Four of these clones were analyzed in detail by hybridization with 16S, 23S, and 4S Beneckea RNA. The observations suggest that the ribosomal genes in Beneckea are linked, but are present in a different order than those in E. coli.
