Mycobacterium tuberculosis L-asparagine permease AnsP1 (AnsP1)

In vitro and mouse studies suggest inhibiting AnsP1 could help treat tuberculosis. In M. tuberculosis, deletion of AnsP1, a transporter that mediates nitrogen assimilation from aspartate, prevented bacterial growth when aspartate was the only nitrogen source. In mice, an M. tuberculosis strain lacking AnsP1 was less infectious than a wild-type strain. Next steps could include identifying compounds that inhibit the AnsP1 transporter.
