Comments [?]

case not <OC:Mycobacteriaceae>
Function An essential GTPase that binds both GDP and GTP, with rapid nucleotide exchange. Plays a role in 16S rRNA processing and 30S ribosomal subunit biogenesis and possibly also in cell cycle regulation and energy metabolism.
else case <OC:Mycobacteriaceae>
Function Exhibits GTPase activity. Binds RNA but is probably not involved in ribosome assembly in mycobacteria.
end case
Subunit Monomer.
case <OC:Mycobacteriaceae>
Subcellular location Cell envelope. Secreted, cell wall.
else case not defined <Property:Membrane> or <Property:Membrane=1>
Subcellular location Cytoplasm. Cell membrane; Peripheral membrane protein.
else case <Property:Membrane=2>
Subcellular location Cytoplasm. Cell inner membrane; Peripheral membrane protein.
end case
Similarity Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. Era GTPase family.
