Functional Importance of Mobile Ribosomal Proteins

Components of L12 stalk. See Methods for the modeling details. Blue: 23S rRNA nucleotide 1030–1124. Magenta: L10. Green: L11. Orange and yellow: a pair of L12 dimers. For clarity, only one L12 dimer is shown. L12 monomers dimerize through their NTD helices, which also bind to L10 CTD. L10 CTD accommodates two (in E. coli) to three (in T. thermophilus) L12 dimers [19]. L10 NTD attaches to 23S rRNA.
