Regulation of a macrolide resistance-beta-galactosidase (ermC-lacZ) gene fusion in Escherichia coli.

RESUMO
A fusion constructed between the putative attenuator plus the first 219 nucleotides of the ermC (erythromycin resistance) structural gene and a 5' terminally deleted lacZ gene produced a moderate, basal level of beta-galactosidase which was increased by erythromycin addition. Another construction containing an intact ermC gene in addition to the fusion produced lower levels of beta-galactosidase, suggesting that the ermC gene product exerts negative feedback control on expression.
