Molecule Alteration Expression
Inherence
Experimental Note Discovered Using In-vivo Testing Model
In Vitro Model Escherichia coli strain HB101 634468
Escherichia coli strain DH5alpha 668369
Bacillus subtilis strain 1A685 1423
Bacillus subtilis strain vectors pHV143 1423
Bacillus ticheniformis strain FD 1402
Experiment for
Molecule Alteration		 Dideoxynucleotide chain-termination method assay
Experiment for
Drug Resistance		 MIC assay
Mechanism Description How could the proposed export function of the Bcr permease account for the bacitracin resistance The transported molecule could be either the substance inactivating the antibiotic or the antibiotic alone. As already observed. some of the metabolites could inhibit the bactericidal activity of bacitracin at very low concentrations. However, in S. subfitis and Escherichia coli strains carrying cloned bcr genes, no substances that could suppress bacitracin activity were detected. It seems that the bacitracin is indeed the target of the Bcr ABC transporter.

Experiment for
Drug Resistance		 MIC assay
Mechanism Description The nucleotide sequence of the Bacillus licheniformis bacitracin-resistance locus was determined. The presence of three open reading frames, bcrA, bcrB and bcrC, was revealed. The BcrA protein shares a high degree of homology with the hydrophilic ATP-binding components of the ABC family of transport proteins. The bcrB and bcrC genes were found to encode hydrophobic proteins, which may function as membrane components of the permease. Apart from Bacillus subtilis, these genes also confer resistance upon the Gram-negative Escherichia coli.
