Regulation of metalloprotease gene expression in Vibrio vulnificus by a Vibrio harveyi LuxR homologue.

abstract：:lisRK encodes a two-component regulatory system in the food pathogen Listeria monocytogenes LO28. Following identification of the operon in an acid-tolerant Tn917 mutant, a deletion in the histidine kinase component was shown to result in a growth phase variation in acid tolerance, an ability to grow in high ethanol c...
