== Publication Abstract from PubMed ==
 +
Mycobacterium tuberculosis (Mtb) is the causative agent of the deadly disease tuberculosis. Iron acquisition, regulation and storage are critical for the survival of this pathogen within a host. Thus, understanding the mechanisms of iron metabolism in Mtb will shed light on its pathogenic nature, as iron is important for infection. Ferritins are a superfamily of protein nanocages that function in both iron detoxification and storage, and Mtb contains both a predicted ferritin and a bacterioferritin. Here, the cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of the ferritin homolog (Mtb BfrB, Rv3841) is reported. An Mtb BfrB crystal grown at pH 6.5 using the hanging-drop vapor-diffusion technique diffracted to 2.50 A resolution and belonged to space group C2, with unit-cell parameters a=226.2, b=226.8, c=113.7 A, beta=94.7 degrees and with 24 subunits per asymmetric unit. Furthermore, modeling the crystal structure of a homologous ferritin into a low-resolution small-angle X-ray scattering (SAXS) electron-density envelope is consistent with the presence of 24 subunits in the BfrB protein cage quaternary structure.
