Intracellular pathogens such as Mycobacterium tuberculosis can promote their survival within infected cells by preventing lysosomal acidification. Here, the authors show that M. tuberculosis secretes a protein that promotes phosphorylation of a subunit of the host vacuolar ATPase, thus inhibiting V-ATPase assembly and lysosomal acidification.
