  1. Abstract:

    Francisella tularensis, a potential bioweapon, causes a rare infectious disease called tularemia in humans and animals. The macrophage growth locus A (MglA) protein from F. tularensis associates with RNA polymerase to positively regulate the expression of multiple virulence factors that are required for its survival and replication within macrophages. The MglA protein was over-produced in Escherichia coli, purified and crystallized. The crystals diffracted to 7.5 angstrom resolution at the Advanced Photon Source, Argonne National Laboratory and belonged to the hexagonal space group P6(1) or P6(5), with unit-cell parameters a = b = 125, c = 54 angstrom.
