Function

GLN1B_MYCTO Involved in nitrogen metabolism via ammonium assimilation. Catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia. Also plays a key role in controlling the ammonia levels within infected host cells and so contributes to the pathogens capacity to inhibit phagosome acidification and phagosome-lysosome fusion. Involved in cell wall biosynthesis via the production of the major component poly-L-glutamine (PLG). PLG synthesis in the cell wall occurs only in nitrogen limiting conditions and on the contrary high nitrogen conditions inhibit PLG synthesis.[UniProtKB:P9WN39]

Publication Abstract from PubMed

A series of imidazo[1,2-a]indeno[1,2-e]pyrazin-4-ones that potently inhibit M. tuberculosis glutamine synthetase (GlnA1) has been identified by high throughput screening. Exploration of this series was performed owing to a short chemistry program. Despite possibly nanomolar inhibitions, none of these compounds was active on whole cell Mtb, suggesting that GlnA1 may not be a suitable target to find new anti-tubercular drugs.
