Lsr2 is a small, basic DNA-bridging protein present in Mycobacterium and related actinomycetes. It is a functional homologue of the H-NS-like proteins [1]. H-NS proteins play a role in nucleoid organisation and also function as a pleiotropic regulator of gene expression [1,2]. This entry represents the dimerization domain found at the N-terminal of Lsr2. Lsr2 dimers show a self-associative propensity allowing chromosome compaction and gene regulation in response to external stress [1-4].	Domain
