Chorismate mutase catalyzes a key step in the shikimate biosynthetic pathway towards phenylalanine and tyrosine. Curiously, the intracellular chorismate mutase of Mycobacterium tuberculosis (MtCM; Rv0948c) has poor activity and lacks prominent active-site residues. However, its catalytic efficiency increases >100-fold on addition of DAHP synthase (MtDS;(More)
DAHP synthase and chorismate mutase catalyze key steps in the shikimate biosynthetic pathway en route to aromatic amino acids. In Mycobacterium tuberculosis, chorismate mutase (MtCM; Rv0948c), located at the branch point toward phenylalanine and tyrosine, has poor activity on its own. However, it is efficiently activated by the first enzyme of the pathway,(More)
Tuberculosis (TB) is a devastating disease that claims millions of lives every year. Hindered access or non-compliance to medication, especially in developing countries, led to drug resistance, further aggravating the situation. With current standard therapies in use for over 50 years and only few new candidates in clinical trials, there is an urgent call(More)
Chorismate mutase catalyzes a key step in the shikimate-biosynthetic pathway and hence is an essential enzyme in bacteria, plants and fungi. Mycobacterium tuberculosis contains two chorismate mutases, a secreted and an intracellular one, the latter of which (MtCM; Rv0948c; 90 amino-acid residues; 10 kDa) is the subject of this work. Here are reported the(More)
The shikimate pathway enzyme chorismate mutase converts chorismate into prephenate, a precursor of Tyr and Phe. The intracellular chorismate mutase (MtCM) of Mycobacterium tuberculosis is poorly active on its own, but becomes >100-fold more efficient upon formation of a complex with the first enzyme of the shikimate pathway,(More)
