摘要：
SarA is a global transcription regulator in S. aureus which regulates the expression of over 120 genes related to quorum sensing, biofilm synthesis, drug resistance and many other important physiological processes during host infection. SarA can bind to the promoter region of agr and other target genes to activate or repress the transcription. The crystal structure of SarA uncovered a MarR protein-like conformation with two symmetrical winged helix domains, while its DNA binding mechanism is still unknown. We have constructed a monomeric DNA binding domain of SarA (SarAΔN19) for the study of the interaction between SarA and DNA with NMR spectroscopy. Here, we report the 1H, 13C and 15N NMR assignment of SarAΔN19/DNA complex which is the first step towards further structure and function analysis.
