Abstract The transcriptional antisilencer VirB acts as a master regulator of virulence gene expression in the human pathogen Shigella flexneri. It binds DNA sequences (virS) upstream of VirB-dependent promoters and counteracts their silencing by the nucleoid-organizing protein H-NS. However. its precise mode of action remains unclear. https://ddqandysyfhi10.timeblog.net/70683102/an-inexact-multiple-recourse-hybrid-fuel-management-model-with-considering-carbon-reduction-requirement-for-a-biofuel-penetrated-heating-system
