1PN8: 30S ribosomal protein S12

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. Determined by electron microscopy at 10.8 Å resolution. Released 15 Jul 2003.
