Mycobacterium species have developed numerous strategies to avoid the antimycobacterial actions of macrophages, enabling them to survive within the generally inhospitable environment of the cell. The recently identified MSMEG_5817 protein from M. smegmatis is highly conserved in Mycobacterium spp. and is required for bacterial survival in macrophages. Here, the cloning, expression, purification and crystallization of MSMEG_5817 is reported. Crystals of MSMEG_5817 were grown in 1.42 M Li2SO4, 0.1 M Tris-HCl pH 7.7, 0.1 M sodium citrate tribasic dihydrate. Native and multiple-wavelength anomalous dispersion (MAD) data sets have been collected and structure determination is in progress.
