Bacterial nucleoid-associated proteins, such as H-NS-like proteins in Enterobacteriaceae, are abundant DNA-binding proteins that function in chromosomal DNA organization and gene transcription regulation. The Mycobacterium tuberculosis Lsr2 protein has been proposed to be the first identified H-NS analogue in Gram-positive
