Figure 1From: Analysis of the function of E. coli 23S rRNA helix-loop 69 by mutagenesisA scheme of E. coli 23S rRNA helix 69. Nucleotides implicated in contacts with 30S subunit are in red [1,3,6]. Proposed contact areas with A and P site tRNAs [1] are shown in yellow and green boxes. Numbers of the pseudouridine residues are indicated according to standard E. coli 23S rRNA numeration.Back to article page
