[[4e1r]] is a 2 chain structure with sequence from [http://en.wikipedia.org/wiki/Mycobacterium_tuberculosis Mycobacterium tuberculosis]. Full crystallographic information is available from [http://oca.weizmann.ac.il/oca-bin/ocashort?id=4E1R OCA].

== Function ==
 +
[https://www.uniprot.org/uniprot/LSR2_MYCTU LSR2_MYCTU] DNA-bridging protein that has both architectural and regulatory roles. Influences the organization of chromatin and gene expression by binding non-specifically to DNA, with a preference for AT-rich sequences, and bridging distant DNA segments. Represses expression of multiple genes involved in a broad range of cellular processes, including major virulence factors or antibiotic-induced genes, such as iniBAC or efpA. May coordinate global gene regulation and virulence. Also protects mycobacteria against reactive oxygen intermediates during macrophage infection by acting as a physical barrier to DNA degradation.<ref>PMID:17590082</ref> <ref>PMID:18187505</ref> <ref>PMID:19237572</ref> <ref>PMID:20133735</ref>
