Subgroups of tuberculosis-causing bacteria can persist even when antibiotics wipe out most of the population. The need to eliminate these persistent subpopulations is one reason why TB treatment regimens are so lengthy.

The protein may be a target for intervention; blocking it might result in less mycobacterial diversity and shorten TB treatment courses.
