Lsr2 and its novel paralogue mediate the adjustment of Mycobacterium smegmatis to unfavorable environmental conditions
Ontology highlight
ABSTRACT: In the present study, we sought to explore the role of Lsr2 as a regulator of transcription in the saprophytic species, M. smegmatis. We used RNA-seq to compare the global transcription profiles of Δlsr2 and wild-type M. smegmatis strains in an attempt to decode Lsr2 regulatory network under optimal conditions or during hypoxia. We show that Lsr2 binds AT-rich regions and mainly acts as a gene repressor, either directly by binding promoter regions or indirectly through DNA-loop formation.
