1. The Mycobacterium tuberculosis glutamate synthase consisting of alpha and beta subunits can be purified in a heterologous Escherichia coli expression system. 2. The beta subunit can be expressed in the soluble protein fraction under low temperature conditions.
3. The alpha subunit enters inclusion bodies in E coli but can be refolded and subsequently purified.
