CC   -!- FUNCTION: An essential GTPase that binds both GDP and GTP, with rapid
CC       nucleotide exchange. Plays a role in 16S rRNA processing and 30S
CC       ribosomal subunit biogenesis and possibly also in cell cycle regulation
CC       and energy metabolism. {ECO:0000255|HAMAP-Rule:MF_00367}.
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00367}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm. Cell membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00367}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00367}.
CC   -!- SIMILARITY: Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like
CC       GTPase superfamily. Era GTPase family. {ECO:0000255|HAMAP-
CC       Rule:MF_00367, ECO:0000255|PROSITE-ProRule:PRU01050}.
