CC -!- FUNCTION: ATPase component of the type III secretion system (T3SS),
CC also called injectisome, which is used to inject bacterial effector
CC proteins into eukaryotic host cells (PubMed:16672607, PubMed:8132449,
CC PubMed:20453832, PubMed:28653671). Acts as a molecular motor to provide
CC the energy that is required for the export of proteins (Probable).
CC Required for type III secretion apparatus (T3SA) formation, proper
CC protein secretion, host cell invasion and virulence (By similarity).
CC May play a critical role in T3SS substrate recognition, disassembly of
CC the effector/chaperone complex and unfolding of the effector in an ATP-
CC dependent manner prior to secretion (By similarity). Required for the
CC stabilization of the major sorting platform component (or C-ring
CC component) (PubMed:25591178). {ECO:0000250|UniProtKB:P0A1B9,
CC ECO:0000250|UniProtKB:P0A1C1, ECO:0000269|PubMed:16672607,
CC ECO:0000269|PubMed:20453832, ECO:0000269|PubMed:25591178,
CC ECO:0000269|PubMed:28653671, ECO:0000269|PubMed:8132449,
CC ECO:0000305|PubMed:16672607, ECO:0000305|PubMed:8132449}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + cellular proteinSide 1 = ADP + phosphate +
CC cellular proteinSide 2.; EC=7.4.2.8;
CC Evidence={ECO:0000305|PubMed:16672607, ECO:0000305|PubMed:8132449};
CC -!- ACTIVITY REGULATION: ATPase activity is negatively regulated by
CC YscL/SctL. {ECO:0000269|PubMed:16672607}.
CC -!- SUBUNIT: The core secretion machinery of the T3SS is composed of
CC approximately 20 different proteins, including cytoplasmic components,
CC a base, an export apparatus and a needle (PubMed:30107569,
CC PubMed:20453832, PubMed:28653671, PubMed:30101242). This subunit is
CC part of the cytosolic complex (PubMed:20453832, PubMed:25591178,
CC PubMed:28653671, PubMed:30101242). Forms homohexamers
CC (PubMed:30101242). Interacts directly with YscL/SctL (stator protein)
CC (PubMed:16672607). YscN assembly requires the presence of YscC/SctC
CC (the secretin), YscJ/SctJ (the outer inner ring protein), YscQ/SctQ
CC (the major sorting platform component), YscK/SctK and YscL/SctL
CC (PubMed:20453832). Interacts with the Yersinia outer protein R (YopR)
CC in a secretion signal-dependent manner (PubMed:17050689).
CC {ECO:0000269|PubMed:16672607, ECO:0000269|PubMed:17050689,
CC ECO:0000269|PubMed:20453832, ECO:0000269|PubMed:25591178,
CC ECO:0000269|PubMed:28653671, ECO:0000269|PubMed:30101242,
CC ECO:0000269|PubMed:30107569}.
CC -!- INTERACTION:
CC P40290; Q01249: yscH; NbExp=2; IntAct=EBI-6502619, EBI-15606767;
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:16672607}.
CC -!- DISRUPTION PHENOTYPE: Deletion mutant secretes neither Yops nor the
CC ruler and needle subunits. {ECO:0000269|PubMed:20453832}.
CC -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family. T3SS ATPase
CC subfamily. {ECO:0000305}.
