Coordinates of S12, L11 proteins and E-site tRNA from 70S crystal structure separately fitted into the Cryo-EM map of E.coli 70S.EF-G.GDPNP complex. The atomic coordinates originally from the E-site tRNA were fitted in the position of the hybrid P/E-site tRNA.
1pn8 is a 3 chain structure with sequence from Thermotoga maritima and Thermus thermophilus. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
RS12_THET8 With S4 and S5 plays an important role in translational accuracy (By similarity).[HAMAP-Rule:MF_00403_B] Interacts with and stabilizes bases of the 16S rRNA that are involved in tRNA selection in the A site and with the mRNA backbone. Located at the interface of the 30S and 50S subunits, it traverses the body of the 30S subunit contacting proteins on the other side and probably holding the rRNA structure together. The combined cluster of proteins S8, S12 and S17 appears to hold together the shoulder and platform of the 30S subunit.[HAMAP-Rule:MF_00403_B]
