CC -!- FUNCTION: ATPase component of the type II secretion system required for
CC the energy-dependent secretion of extracellular factors such as
CC proteases and toxins from the periplasm. Acts as a molecular motor to
CC provide the energy that is required for assembly of the pseudopilus and
CC the extrusion of substrates generated in the cytoplasm.
CC {ECO:0000250|UniProtKB:Q00512}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + cellular proteinSide 1 = ADP + phosphate +
CC cellular proteinSide 2.; EC=7.4.2.8;
CC Evidence={ECO:0000250|UniProtKB:P37093};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000250|UniProtKB:P37093};
CC -!- SUBUNIT: Forms homooligomers; most probably hexamers (By similarity).
CC Interacts with GspL (By similarity). {ECO:0000250|UniProtKB:P37093,
CC ECO:0000250|UniProtKB:Q00512}.
CC -!- INTERACTION:
CC P45759; P60422: rplB; NbExp=2; IntAct=EBI-1132437, EBI-543515;
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000250|UniProtKB:Q00512}. Note=Membrane association is not an
CC intrinsic property but requires the GspL gene product.
CC {ECO:0000250|UniProtKB:Q00512}.
CC -!- INDUCTION: Silenced by the DNA-binding protein H-NS under standard
CC growth conditions. {ECO:0000269|PubMed:11118204}.
CC -!- MISCELLANEOUS: Part of a cryptic operon that encodes proteins involved
CC in type II secretion machinery in other organisms, but is not expressed
CC in strain K12.
CC -!- SIMILARITY: Belongs to the GSP E family. {ECO:0000305}.
