DE RecName: Full=GTPase Era {ECO:0000255|HAMAP-Rule:MF_00367}; GN Name=era {ECO:0000255|HAMAP-Rule:MF_00367}; GN OrderedLocusNames=HPP12_0523; OS Helicobacter pylori (strain P12). OC Bacteria; Proteobacteria; Epsilonproteobacteria; Campylobacterales; OC Helicobacteraceae; Helicobacter. OX NCBI_TaxID=570508; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=P12; RA Fischer W., Windhager L., Karnholz A., Zeiller M., Zimmer R., Haas R.; RT "The complete genome sequence of Helicobacter pylori strain P12."; RL Submitted (OCT-2008) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: An essential GTPase that binds both GDP and GTP, with CC rapid nucleotide exchange. Plays a role in 16S rRNA processing and CC 30S ribosomal subunit biogenesis and possibly also in cell cycle CC regulation and energy metabolism. {ECO:0000255|HAMAP- CC Rule:MF_00367}. CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00367}. CC -!- SUBCELLULAR LOCATION: Cytoplasm. Cell inner membrane CC {ECO:0000255|HAMAP-Rule:MF_00367}; Peripheral membrane protein CC {ECO:0000255|HAMAP-Rule:MF_00367}. CC -!- SIMILARITY: Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin- CC like GTPase superfamily. Era GTPase family. {ECO:0000255|HAMAP- CC Rule:MF_00367}. CC -!- SIMILARITY: Contains 1 Era-type G (guanine nucleotide-binding) CC domain. {ECO:0000305}. CC -!- SIMILARITY: Contains 1 KH type-2 domain. {ECO:0000255|HAMAP- CC Rule:MF_00367}.
