A new gene from Bacillus cereus has been characterized which codes for a protein conferring resistance to the antibiotic zwittermicin A produced by some strains of the bacteria. The resistance gene, designated zmaR, is found to be present in almost all strains of the bacteria which are known to natively have the ability to synthesize zwittermicin A, and thus allows tests for the presence of the gene to serve as a test to be used with new strains to assay for zwittermicin A production. The gene also has use in increasing production of the antibiotic by producing strains.
