Crystallization and preliminary X-ray crystallographic studies of DnaJ from Streptococcus pneumoniae
DnaJ from Streptococcus pneumoniae (SpDnaJ) is involved in the infectious disease process and is being developed as a potential vaccine to prevent bacterial infection. Here the expression, purification, crystallization and preliminary crystallographic analysis of SpDnaJ are reported.

The Escherichia coli cyclic AMP receptor protein (CRP) is a prokaryotic global transcription activator protein that controls the expression of many different genes. cAMP-free D53H CRP crystals were obtained and diffracted at a resolution of 2.9 Å. Based on the systematic absences of the crystals, the likely space group is P212121 with the unit-cell parameters a = 76.66, b = 152.14, and c = 176.11 Å. The asymmetric unit was confirmed to contain four protein dimers with a Matthews coefficient of 2.71 Å3 Da-1 and a solvent content of 54.68%.
