glutamine synthetase (type I)  M-CSA #537

Glutamine synthetase catalyses the condensation reaction of ammonium and glutamate to form glutamine, using ATP. This is observed in the early stages of infection by Mycobacterium tuberculosis as an extracellular component in the synthesis of poly(L-glutamine-L-glutamate) chains requires for cell wall formation. Therefore this enzyme is an important drug target for halting tuberculosis infection.
