CC -!- FUNCTION: A translation factor that gates the progression of the 70S
CC ribosomal initiation complex (IC, containing tRNA(fMet) in the P-site)
CC into the translation elongation cycle by using a mechanism sensitive to
CC the ATP/ADP ratio. Binds to the 70S ribosome E-site where it modulates
CC the state of the translating ribosome during subunit translocation. ATP
CC hydrolysis probably frees it from the ribosome, which can enter the
CC elongation phase. {ECO:0000255|HAMAP-Rule:MF_00847}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00847};
CC -!- SUBUNIT: Monomer. Probably contacts ribosomal proteins L1, L5, L33 and
CC S7, the 16S and 23S rRNA and the P-site containing tRNA(fMet).
CC {ECO:0000255|HAMAP-Rule:MF_00847}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00847}.
CC Note=Associates with ribosomes and polysomes. {ECO:0000255|HAMAP-
CC Rule:MF_00847}.
CC -!- DOMAIN: The arm domain is inserted in the first ABC transporter domain.
CC Probably contacts ribosomal protein L1. {ECO:0000255|HAMAP-
CC Rule:MF_00847}.
CC -!- DOMAIN: The P-site tRNA interaction motif (PtIM domain) probably
CC interacts with the P-site tRNA(fMet) as well as the 23S rRNA.
CC {ECO:0000255|HAMAP-Rule:MF_00847}.
CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. ABCF family.
CC Translational throttle EttA subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_00847, ECO:0000305}.
