tsftranslation elongation factor EF-Ts
Escherichia coli str. K-12 substr. MG1655
(Microbial infection) Promotes the tRNase activity of CdiA-CT from E.coli strain NC101 (CdiA-CT-NC101); required in vivo and in vitro. Probably loads charged tRNA onto EF-Tu, making more ternary GTP-EF-Tu-aa-tRNA complexes. The guanine nucleotide exchange factor capacity of this protein does not seem to be needed as no GTP hydrolysis occurs during tRNA cleavage. CdiA-CT is the toxic component of a toxin-immunity protein module, which functions as a cellular contact-dependent growth inhibition (CDI) system. CDI modules allow bacteria to communicate with and inhibit the growth of closely related neighboring bacteria in a contact-dependent fashion (PubMed:28973472). EF-Ts interacts with at least 2 different toxic CT domains, the 2 toxins are different and degrade tRNA at different positions (PubMed:28973472, PubMed:28223500).
