WebOverview of Elongation Stage Of Translation. The process of translation is the final process in the central dogma that results in the production of the protein chain with the help of ribosomal subunits, accessory enzymes, and associative units. The expression of these proteins in bringing various observable characters that define the features ... WebProkaryotic (EF-Tu) and eukaryotic (EF-1α) elongation factors are single-subunit proteins with molecular masses of 45 and 50 kDa, respectively. The proteins may also function as a complex with GTP-exchanging subunits (prokaryotic EF-Ts and the eukaryotic EF-1βγδ complex). More details on the eukaryotic complex will be given in Section V.
WebEF-G on the ribosome Binding to L7/L12. L7/L12 is only a multicopy protein on the large ribosomal subunit of the bacterial ribosome that binds to certain GTPases, like Initiation Factor 2, Elongation factor-Tu, Release Factor 3, and EF-G. Specifically, the C-terminal of L7/L12 will bind to EF-G and is necessary for GTP hydrolysis.. Interaction with the … WebAbstract.
