Mycobacterium tuberculosis MycP1 protease plays a dual role in regulation of ESX-1 secretion and virulence

Mycobacterium tuberculosis uses the ESX-1 secretion system to deliver virulence proteins during infection of host cells. Here we report a mechanism of posttranscriptional control of ESX-1 mediated by MycP1, a M. tuberculosis serine protease. We show that MycP1 is required for ESX-1 secretion but tha...
