DNA-binding protein H-NS Protein, SerRatia marcescens, Recombinant (His)

A DNA-binding protein implicated in transcriptional repression and chromosome organization and compaction. Binds nucleation sites in AT-rich DNA and bridges them, forming higher-order nucleoprotein complexes and condensing the chromosome. As many horizontally transferred genes are AT-rich, it plays a central role in silencing foreign genes. A subset of genes are repressed by H-NS in association with other proteins. DNA-binding protein H-NS Protein, SerRatia marcescens, Recombinant (His) is expressed in E. coli expression system with N-6xHis tag. The predicted molecular weight is 19.5 kDa and the accession number is P18955.
