The X-ray crystal structure of PA1607 from Pseudomonas aureginosa at 1.9 Å resolution-a putative transcription factor.

The structure of the PA1607 protein from Pseudomonas aureginosa was determined at 1.85 Å resolution using the Se-Met multiwavelength anomalous diffraction (MAD) technique. PA1607 forms a dimer and adopts a winged-helix motif similar to the MarR family of transcription regulators, though it has an unusual dimerization profile. The DNA-binding regions and a putative metal-binding site are not conserved in PA1607. [ABSTRACT FROM AUTHOR]
