Purification crystallization and preliminary X-ray diffraction analysis of the C-terminal fragment of the MvfR protein from Pseudomonas aeruginosa

摘要

The LysR-type transcriptional regulator MvfR plays a critical role in Pseudomonas aeruginosa pathogenicity via the transcriptional regulation of multiple quorum-sensing-regulated virulence factors. The protein also controls pathogenic type VI secretion loci. MvfRC87, a 242-residue C-­terminal segment of MvfR, was produced in Escherichia coli, purified and crystallized. X-­ray diffraction data were collected using synchrotron radiation and crystallographic parameters were determined.
