RT tuberculosis from oxidative and acidic stress.";
RL Structure 18:1353-1363(2010).
CC -!- FUNCTION: Required for M.tuberculosis resistance to oxidative stress in
CC addition to its role in resistance to acid, which is essential for
CC virulence. It protects M.tuberculosis against phagolysosomal
CC concentrations of acid and maintains its intrabacterial pH when
CC phagocytosed by IFN-gamma-activated macrophages.
CC {ECO:0000269|PubMed:18641659, ECO:0000269|PubMed:20947023}.
CC -!- ACTIVITY REGULATION: Inhibited by reducing agents and activated during
CC exposure to oxidative stress. {ECO:0000269|PubMed:20947023}.
CC -!- SUBUNIT: Monomer. {ECO:0000269|PubMed:20947023}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000305}.
CC -!- PTM: Autocleaved. The autocleavage activity is significant only when no
CC reducing agent is present in buffers.
CC -!- DISRUPTION PHENOTYPE: Disruption leads to an increased sensitivity to
CC acid and fails to maintain intrabacterial pH in acid in vitro and in
CC activated macrophages. Growth is also severely attenuated in mice.
CC {ECO:0000269|PubMed:18641659}.
CC -!- MISCELLANEOUS: Disulfide bond increases the proteolytic activity by
CC stabilizing the protease in the conformation in which the active site
CC residues are properly positioned for substrate binding and catalysis.
CC -!- SIMILARITY: Belongs to the peptidase S1C family. {ECO:0000305}.
