Era is a highly conserved GTPase essential for bacterial growth. The N-terminal part of Era contains a conserved GTPase domain, whereas the C-terminal part of the protein contains anRNA- andmembrane-binding domain, theKH domain. To investigate whether the binding of Era to 16S rRNA and membrane requires its GTPase activity and whether the GTPase domain is essential for these acti-vities, the N- and C-terminal parts of the Streptococ-cus pneumoniaeEra –Era-N(aminoacids 1–185) andEra-C (amino acids 141–299), respectively – were expressed and purified. ...
