Crystal structure of putative DNA binding protein SP_1288 from Streptococcus pygenes

Overview

The crystal structure of the putative DNA-binding protein SP_1288, (gi/15675166, also listed as gi/28895954) from Streptococcus pyogenes has, been determined by X-ray crystallography to a resolution of 2.3 A using, anomalous diffraction data at the Se peak wavelength. SP_1288 belongs to a, family of proteins whose cellular function is associated with the signal, recognition particle; no structural information has been available until, now about the members of the family. Crystallographic analysis revealed, that the overall fold of SP_1288 consists exclusively of alpha-helices and, that 75% of the structure has good similarity to domain 4 of the sigma, subunit of RNA polymerase. This suggests its possible involvement in the, biochemical function of transcription initiation, which includes, interaction with DNA.
