Characterization of the membrane sensor PenJ for beta-lactam antibiotics from Bacillus licheniformis by amino acid substitution.

abstract：:An autonomous impala transposon trapped in Fusarium oxysporum by insertion within the niaD gene encoding nitrate reductase was introduced in the genome of the fungus Penicillium griseoroseum, a producer of pectinase enzymes. Through a phenotypic assay, we demonstrate that this element is able to excise from the niaD g...
