CC   -!- FUNCTION: One of several proteins that assist in the late maturation
CC       steps of the functional core of the 30S ribosomal subunit. Helps
CC       release RbfA from mature subunits. May play a role in the assembly of
CC       ribosomal proteins into the subunit. Circularly permuted GTPase that
CC       catalyzes slow GTP hydrolysis, GTPase activity is stimulated by the 30S
CC       ribosomal subunit. {ECO:0000255|HAMAP-Rule:MF_01820}.
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01820};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01820};
CC   -!- SUBUNIT: Monomer. Associates with 30S ribosomal subunit, binds 16S
CC       rRNA. {ECO:0000255|HAMAP-Rule:MF_01820}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01820}.
CC   -!- SIMILARITY: Belongs to the TRAFAC class YlqF/YawG GTPase family. RsgA
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_01820}.
