Abstract
Bacillus anthracis 590 having an inducibla resistance determinant to MLS antibiotics was isolated from a soli sample in Korea. The resistance gene (ernJ) was cloned by Southern blotting of chromosomal DNA fragment digested by various restriction enzymes and coloy hybridization method and the cloned plasmid was named as pBA423. The size of inserted DNA fragment of pBS42 vector was about 2.9 kb and the DNA sequence of the subcloned fragment (Hinc II-Hinc II, 1.4kb) WAS determined. The DNA sequence of ernJ was composed of 357 bp for leader region and 861 bp for the structural gene. Because the leader sequence of ernJ was homologous to that of ermK, the expression of ernJ is also thought to be controlled by a transcriptionl attenuation mechanism.
