Purification, crystallization and preliminary X-ray analysis of SGR6054, a Streptomyces homologue of the mycobacterial integration host factor mIHF

A Streptomyces homologue of the mycobacterial integration host factor mIHF was heterologously produced, purified and crystallized in the presence of a 16-mer duplex DNA by the sitting-drop vapour-diffusion method. The best crystal diffracted X-rays to 2.22 Å resolution and belonged to space group C2.
