1 | FLEXIBLE FITREALCross-correlation | METHOD--Flexible fitting REFINEMENT PROTOCOL--Atom models of the 23S and 5S rRNAs were built using the software S2S and modeRNA, with the crystal structures of the 50S subunits from E. coli (PDB ID- 2AW4) and Thermus thermophilus (PDB ID- 2J01) as template. Models of ribosomal proteins, L1, L3, L4, L6, L10, L13, L14, L15, L17, L19, L20, L21, L22, L23, L24, L27, L29, L30, L31, L32, L33, L34, L35 and L36 were downloaded from the SWISS-MODEL Repository. The others, including L2, L5, L11, L16, L18 and L28 were modeled using MODELLER with crystal structures of E. coli and T. thermophilus 50S subunits as templates.The combined atomic model of the B. subtilis 50S subunit was docked into a high resolution mature 50S density map and optimized using MDFF. This optimized model was docked into the EM density using Chimera and flexible fitted into the density using MDFF.
