CC   -!- FUNCTION: Required for accurate and efficient protein synthesis under
CC       certain stress conditions. May act as a fidelity factor of the
CC       translation reaction, by catalyzing a one-codon backward translocation
CC       of tRNAs on improperly translocated ribosomes. Back-translocation
CC       proceeds from a post-translocation (POST) complex to a pre-
CC       translocation (PRE) complex, thus giving elongation factor G a second
CC       chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP-
CC       dependent manner. {ECO:0000255|HAMAP-Rule:MF_00071}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=GTP + H2O = GDP + H(+) + phosphate; Xref=Rhea:RHEA:19669,

CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00071}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00071}; Cytoplasmic side {ECO:0000255|HAMAP-Rule:MF_00071}.
CC   -!- SIMILARITY: Belongs to the TRAFAC class translation factor GTPase
CC       superfamily. Classic translation factor GTPase family. LepA subfamily.
